Adjustments for non-telephone bias in random-digit-dialling surveys.
Telephone surveys are widely used in the U.S.A. for the study of health-related topics. They are subject to 'coverage bias' because they cannot sample households that do not have telephones. Although only around 5 per cent of households do not have a telephone, rates of telephone coverage show substantial variation by geography, demographic factors and socio-economic factors. In particular, lack of telephone service is more common among households that contain ethnic and racial minorities or that have lower socio-economic status with fewer opportunities for access to medical care and poorer health outcomes. Thus, failure to adequately account for households without telephones in health surveys may yield estimates of health outcomes that are misleading, particularly in states with at least moderate telephone non-coverage. The dynamic nature of the population of households without telephones offers a way of accounting for such households in telephone surveys. At any given time the population of telephone households includes households that have had a break or interruption in telephone service. Empirical results strongly suggest that these households are very similar to households that have never had telephone service. Thus, sampled households that report having had an interruption in telephone service may be used also to represent the portion of the population that has never had telephone service. This strategy can lead to a reduction in non-coverage bias in random-digit-dialling surveys. This paper presents two methods of adjusting for non-coverage of non-telephone households. The effectiveness of these methods is examined using data from the National Health Interview Survey. The interruption-in-telephone-service methods reduce non-coverage bias and can also result in a lower mean squared error. The application of the interruption-in-telephone-service methods to the National Immunization Survey is also discussed. This survey produces estimates for the 50 states and 28 urban areas. The interruption-in-telephone-service estimates tend be slightly lower than estimates resulting from poststratification and from another non-coverage adjustment method. The results suggest that the reduction in bias is greatest for variables that are highly correlated with the presence or absence of telephone service.

Pagers combined with telephones improve successful follow-up from a pediatric emergency department.
OBJECTIVE: To determine whether there is a significant difference in initial successful contact when attempting follow-up of patients discharged from a pediatric emergency department (ED) using either pagers or the telephone. In addition, to evaluate whether the combination of both pager and telephone follow-up is more successful than telephone follow-up alone when confined to a 2-hour period. DESIGN AND SETTING: A prospective comparison of intervention and control groups taken from convenience samples of patients seen in an ED of an urban, tertiary care children's hospital. PARTICIPANTS: One hundred eighty-five patients whose families had access to both a pager and a telephone (intervention group) and 112 patients whose families had access to only a telephone (control group) were enrolled. INTERVENTION: Before discharging the patient from the ED, the investigators verified a pager number and/or a best contact telephone number for a follow-up telephone call. Participants were divided into 2 groups. The intervention group consisted of caretakers with both pagers and telephones. The control group consisted of caretakers with only telephones. On even calendar days after ED visits, intervention group caretakers were paged initially from 11:00 AM to 11:59 AM. On odd calendar days, intervention group caretakers were telephoned initially from 11:00 AM to 11:59 AM. Successful contact was defined as communication with a family member or guardian over the age of 18. If the caretaker spoke only Spanish, a translator was used. In a crossover design with the intervention group, if contact was unsuccessful after 1 hour, the alternative mode of communication was used at noon. Control group caretakers were telephoned from 11:00 AM to 11:59 AM. If telephone contact was unsuccessful, they were called again 1 hour later. RESULTS: Two hundred forty-six (36%) of 685 of the convenience sample of caretakers had access to both a pager and a telephone. Fifty-two (55%) of 94 intervention caretakers were contacted initially using pagers versus 47 (52%) of 91 intervention caretakers contacted initially by telephones. Overall successful contact of intervention caretakers (telephones and pagers) was 145 (78%) of 185 when confined to a 2-hour time period. In contrast, overall successful contact of control caretakers was 68 (61%) of 112 when confined to a 2-hour time period. Successful contact was greater with the intervention caretakers than with control caretakers (78% vs 61%). CONCLUSIONS: No significant difference in successful contact was seen whether paged or telephoned initially. The combination of both pagers and telephone follow-up was more successful than telephone follow-up alone when confined between 11:00 AM to 1:00 PM.

The implementation of a call-back system reduces the doctor's workload, and improves accessibility by telephone in general practice.
BACKGROUND: In a general practice in The Netherlands, the demand for direct telephone consultation with the doctor became extreme, which resulted in poorly managed consultations, and poor telephone access due to busy lines. A call-back telephone appointment system was therefore introduced: all calls are answered and, when possible, managed by the practice assistant. If the assistant feels incapable, or if the patient prefers to speak to the doctor, a telephone appointment is scheduled, at which time the doctor returns the patient's call. OBJECTIVE: Our aim was to evaluate the effects of a call-back telephone appointment system on doctors' workload and patients' telephone access to doctors. METHODS: Telephone consultation data over 10 weeks were selected before and after the introduction of the call-back telephone appointment system. The outcomes measured were: number and duration of telephone calls to doctors, the reason for each call and how often telephone lines were engaged during the specified telephone hour. RESULTS: The number of calls requiring the doctor's attention was reduced by 59% and total time spent on the telephone by the GPs was reduced by 39%. This reduction is explained by a change in the reasons for calling. Telephone accessibility improved, as busy telephone lines were no longer an issue. CONCLUSION: The call-back telephone appointment system is superior to the previously used open access telephone hour.

Enhancing adherence following abnormal Pap smears among low-income minority women: a preventive telephone counseling strategy.
BACKGROUND: Although the incidence of precancerous conditions of the cervix has recently been increasing, prompt initial and long-term follow-up care can effectively reduce unnecessary morbidity and mortality. For example, the 4-year survival rates among those individuals at greatest risk for cervical cancer (i.e., minority women of low socioeconomic status) approach 95% with early detection. Women who present with advanced disease have a much poorer outlook (0%-39% survival). Yet, high-risk individuals are least likely to adhere to recommended diagnostic regimens. PURPOSE: We tested the effectiveness of a brief telephone counseling intervention directed to low-income, inner-city women after they had received an abnormal Pap smear result. The women were counseled on the importance of having an initial and 6-month repeat follow-up diagnostic procedure (i.e., colposcopic examination of the cervix). METHODS: A randomized trial design was used to compare the effects on these women of telephone counseling with (n = 192) or without (n = 203) a booster counseling telephone call prior to the appointment for a repeat colposcopy 6 months later, with a telephone appointment confirmation/reminder call (n = 216) and with standard care (i.e., no telephone contact) (n = 217). The telephone counseling protocol probed for and addressed three psychologic barriers to adherence (i.e., attendance at appointment for colposcopy examination): 1) encoding/expectancy (e.g., did the patient understand her risk of developing cervical cancer?); 2) affective/emotional (e.g., was the woman worried about the condition and its consequences?); and 3) self-regulatory/practical (e.g., was the woman likely to forget medical appointments?). Logistic regression was used to analyze the effects of the intervention group and the type of psychologic barriers elicited on colposcopy adherence. RESULTS: The results of logistic regression analysis (using those who received an appointment confirmation/reminder telephone call as the comparison group) revealed that telephone counseling produced significantly higher adherence rates to the initial colposcopy visit compared with telephone confirmation (300 [76%] of 395 women versus 147 [68%] of 216; odds ratio [OR] = 1.50; 95% confidence interval [CI] = 1.04-2.17). Additionally, standard care resulted in significantly lower adherence rates than did telephone confirmation (109 [50%] of 217 women versus 147 [68%] of 216; OR = 0.47; 95% CI = 0.32-0.73). Regarding attendance at the 6-month repeat colposcopy appointments, the 80 patients who had received telephone counseling prior to the initial visit (and were recommended for follow-up colposcopy) were significantly more likely to adhere than were the 47 patients who had received telephone confirmation (49 [61%] of 80 women versus 17 [36.2%] of 47; OR = 2.70; 95% CI = 1.15-6.51). The 6-month adherence rates for patients in the telephone confirmation group and the standard care group (n = 30) were low and did not differ significantly (17 [36.2%] of 47 women versus nine [30.0%] of 30; OR = 1.08; 95% CI = 0.40-2.89). Forgetting medical appointments (OR = 0.31; 95% CI = 0.19-0.51) and having scheduling conflicts (OR = 0.45; 95% CI = 0.28-0.72) were also associated with lower rates of adherence. CONCLUSION: The use of telephone counseling appears to be an effective strategy for enhancing initial and long-term adherence to a follow-up cervical diagnostic procedure in a traditionally underserved population. Patients who respond to a positive Pap test result with a particular profile of psychologic barriers may require more intensive and targeted counseling interventions.

Assessing inner-city patients' hospital experiences. A controlled trial of telephone interviews versus mailed surveys.
OBJECTIVES: Obtaining accurate and representative patient-centered data may be difficult among poor, inner-city patients because of changing addresses, variable access to telephones, and a higher prevalence of illiteracy than in the populations in which many survey instruments were developed and tested. Assumptions about the usefulness of mailed surveys versus telephone interviews may not hold for the urban poor. Therefore, identifying the most efficient mode of survey administration in this population becomes an important methodological question. METHODS: We conducted a randomized trial of patients discharged from the inpatient medicine service of an urban teaching hospital to compare telephone interview with mailed self-administration of a detailed instrument for measuring patients' experiences with hospital care. Our primary outcomes were response rate, missing data, and data collection costs. Patients were excluded if they were not discharged to home or were mentally or physically unable to complete mailed or telephone interviews. The research assistant contacted eligible patients while hospitalized, informed them of the postdischarge survey, and obtained current phone numbers and addresses. Patients then were randomized to receive a 116-item satisfaction survey via one of two survey methods: mail-first (mailed surveys with follow-up on nonrespondents by telephone) or telephone-first (telephone interviews with follow-up of nonrespondents by mail). RESULTS: Of the 252 patients enrolled, 130 were randomized to the mail-first and 122 to the telephone-first method. Response rates were higher with the telephone-first (73%) compared with the mail-first method (50%; P < 0.0001). Surveys obtained by the telephone-first method had fewer missing data (0.7 +/- 2.39) for those items not involved in skip patterns compared with the mail-first method (7.1 +/- 12.3; P < 0.001) and were 42% less expensive per completed survey ($26.32 versus $37.35; P < 0.0001). CONCLUSIONS: In this survey of patients served by an urban teaching hospital, a strategy of telephone interviews with mail follow-up proved less expensive and yielded a higher response rate with more complete data than using a method where mailed surveys were followed by back-up telephone interviews. In addition, we believe that the improved response rate for telephone interviews compared with those reported in the literature for similar populations is the result of informing inpatients of the survey and obtaining telephone numbers and addresses in the hospital.

The feasibility of collecting drug abuse data by telephone.
An evaluation was made of the use of telephone survey methods to collect illicit drug use data. Using data from a national survey that collects data by personal interviews, marijuana and cocaine use prevalence rates among households with telephones and those without were compared in order to assess coverage errors in telephone surveys. Drug use rates were substantially higher among households without telephones, with 24.9 percent of those living in households without telephones reporting use of marijuana in the past year, compared with only 9.4 percent of persons living in households with telephones. Trends in drug use were divergent, with substantial decreases in use occurring between 1985 and 1988 in households with telephones, but not in those without. National prevalence patterns and trends among households with telephone appear to be consistent with national patterns and trends in the total household population, because about 93 percent of the population lives in households with telephones. However, surveys conducted by telephone were found to produce underestimates of illicit drug use prevalence. In a 1988 national telephone survey, estimated rates of past year use were 5.2 percent for marijuana and 1.4 percent for cocaine. Comparable data from a personal visit survey (including only households with telephones and reedited and reweighted to control for differences in data collection protocols) were 8.0 percent for marijuana and 3.1 percent for cocaine use. Comparisons with several other telephone surveys collecting illicit drug use data showed similar results. Based on these results, researchers are advised to use caution in using telephone surveys to produce drug use prevalence estimates.

Telephone consultations in general practice: an additional or alternative service?
BACKGROUND: There is conflicting evidence about whether telephone consultations in general practice represent additional or alternative contacts with the general practitioner. AIM: A study set out to assess the characteristics of patients using the telephone to consult the general practitioner and whether telephone consultations were used as an additional or an alternative service to surgery consultations during surgery hours. METHOD: The study took place in one practice that has run a 'phone-in clinic' for five years. A questionnaire on perceptions of and attitudes towards telephone consultations was sent to 259 patients who consulted the general practitioner by telephone and to an age-sex matched group of patients whose medical records indicated that they had never consulted the general practitioner by telephone. For both groups, numbers of repeat prescriptions and consultations in the preceding year were determined from medical records. RESULTS: Those who consulted the doctor by telephone were significantly more likely to be aware of the phone-in clinic, to have a telephone at home, to have children aged under five years at home and to be receiving repeat prescriptions and repeat prescriptions for psychotropic drugs compared with those who had never consulted by telephone. Eleven of 226 patients who consulted be telephone (5%) indicated that they would definitely not have made a surgery appointment or home visit request (that is, they represented additional general practitioner workload) while 120 (53%) used the telephone consultation as an alternative to making a surgery appointment and 22 (10%) used the telephone consultation as an alternative to requesting a home visit. CONCLUSION: It appears that the telephone service was being used largely as an alternative access point to the doctor. General practitioners should not be apprehensive about the possible increase in workload generated by introducing telephone consultations, for example in phone-in clinics.

Assessing depression in primary care with the PHQ-9: can it be carried out over the telephone?
BACKGROUND: Telephone assessment of depression for research purposes is increasingly being used. The Patient Health Questionnaire 9-item depression module (PHQ-9) is a well-validated, brief, self-reported, diagnostic, and severity measure of depression designed for use in primary care (PC). To our knowledge, there are no available data regarding its validity when administered over the telephone. OBJECTIVE: The aims of the present study were to evaluate agreement between self-administered and telephone-administered PHQ-9, to investigate possible systematic bias, and to evaluate the internal consistency of the telephone-administered PHQ-9. METHODS: Three hundred and forty-six participants from two PC centers were assessed twice with the PHQ-9. Participants were divided into 4 groups according to administration procedure order and administration procedure of the PHQ-9: Self-administered/Telephone-administered; Telephone-administered/Self-administered; Telephone-administered/Telephone-administered; and Self-administered/Self-administered. The first 2 groups served for analyzing the procedural validity of telephone-administered PHQ-9. The last 2 allowed a test-retest reliability analysis of both self- and telephone-administered PHQ-9. Intraclass correlation coefficient (ICC) and weighted kappa (for each item) were calculated as measures of concordance. Additionally, Pearson's correlation coefficient, Student's t-test, and Cronbach's alpha were analyzed. RESULTS: Intraclass correlation coefficient and weighted kappa between both administration procedures were excellent, revealing a strong concordance between telephone- and self-administered PHQ-9. A small and clinically nonsignificant tendency was observed toward lower scores for the telephone-administered PHQ-9. The internal consistency of the telephone-administered PHQ-9 was high and close to the self-administered one. CONCLUSIONS: Telephone and in-person assessments by means of the PHQ-9 yield similar results. Thus, telephone administration of the PHQ-9 seems to be a reliable procedure for assessing depression in PC.

Effectiveness and cost-effectiveness of letters, automated telephone messages, or both for underimmunized children in a health maintenance organization.
BACKGROUND: Immunization rates have improved in the United States, but are still far from the national 90% goal for the year 2000. There is scant evidence about the effectiveness and costs of automated telephone messages to improve immunization rates among privately insured children. OBJECTIVE: To evaluate the effectiveness and cost-effectiveness of sending letters, automated telephone messages, or both to families of underimmunized 20-month-olds in a health maintenance organization (HMO). METHODS: In this randomized trial, underimmunized 20-month-olds identified by the HMO's computerized immunization tracking system were assigned to one of four interventions: 1) an automated telephone message alone; 2) a letter alone; 3) an automated telephone message followed by a letter 1 week later; and 4) a letter followed by an automated telephone message 1 week later. The primary outcome was receipt of any needed immunization by 24 months of age. Decision analysis was used to evaluate the projected cost-effectiveness of the alternative strategies. RESULTS: A total of 648 children were randomized. A letter followed by a telephone message (58% immunized) was significantly better than either a letter alone (44% immunized) or a telephone message alone (44% immunized). A telephone message followed by a letter (53% immunized) also was more effective than either alone, although the differences were not statistically significant. Among a similar comparison group that received no systematic intervention, 36% were immunized. The estimated cost per child immunized was $7.00 using letters followed by automated telephone messages, $9.80 using automated telephone messages alone, and $10.50 using letters alone. Under alternative cost assumptions for automated telephone messages and mailed messages, the cost per child immunized ranged from $2.20 to $6.50. CONCLUSIONS: For underimmunized 20-month-olds in this HMO setting, letters followed by automated telephone messages were more effective and cost-effective than either message alone. The cost-effectiveness of automated telephone messages and letters may vary widely depending on the setting, and choices among strategies should be tailored to the populations being served.

Telephone coverage and health survey estimates: evaluating the need for concern about wireless substitution.
OBJECTIVES: We sought to determine whether the exclusion of adults without landline telephones may bias estimates derived from health-related telephone surveys. METHODS: We took data from the 2004 and 2005 National Health Interview Survey and used logistic regression to compare the odds of behavioral risk factors and health care service use for adults with landline telephones to those for adults with only wireless telephones and adults without any telephone service. RESULTS: When interviewed, 7.2% of adults, including those who did and did not have wireless telephones, did not have landline telephones. Relative to adults with landline telephones, adults without landline telephones had greater odds of smoking and being uninsured, and they had lower odds of having diabetes, having a usual place for medical care, and having received an influenza vaccination in the past year. CONCLUSIONS: As people substitute wireless telephones for landline telephones, the percentage of adults without landline telephones has increased significantly but is still low, which minimizes the bias resulting from their exclusion from telephone surveys. Bias greater than 1 percentage point is expected only for estimates of health insurance, smoking, binge drinking, having a usual place for care, and receiving an influenza vaccination.

Telephone care as an adjunct to routine medical follow-up. A negative randomized trial.
CONTEXT: In 1992, a randomized trial at one outpatient clinic demonstrated that making telephone appointments part of routine medical follow-up could save money and reduce hospitalization. OBJECTIVE: To ascertain the effects of telephone care in other clinics. DESIGN: Consenting patients of 20 physicians were randomly assigned to receive telephone care or usual care. SETTING: Veterans Affairs General Medical Clinics in Denver, Colorado, and Sioux Falls, South Dakota. PATIENTS: 512 predominately male elderly veterans (mean age, 68 years) who had a broad range of chronic medical conditions. INTERVENTION: At the intake clinic visit, the recommended revisit interval (e.g., return in 3 months) for telephone care patients was doubled (e.g., return in 6 months) and three intervening telephone appointments were scheduled. Three telephone appointments were also scheduled at all subsequent clinic visits. MAIN OUTCOME MEASURES: Utilization of services and self-reported health status. RESULTS: More than 2000 calls were made during the 2-year study period. Although the revisit interval was longer for telephone care patients after the intake visit (as was expected), it was the same for both telephone care and usual care patients after all subsequent visits, despite the scheduling of three telephone appointments for telephone care patients. The intervention had no effect on self-reported health status, hospital admission, or number of deaths. The intervention also had no effect on the total number of clinic visits, outpatient laboratory tests, or radiologic tests. Telephone care patients had fewer unscheduled visits than did usual care patients (2.0 vs. 2.8 visits/patient; P = 0.01). CONCLUSION: Telephone care had little effect in this study. Instead of providing a way to maintain contact with patients without requiring them to appear in clinic frequently, telephone appointments became simply an additional service.

Implantable cardioverter defibrillators and cellular telephones: is there any interference?
The aim of our study was to consider cellular telephone interference using different cellular telephones and implantable cardioverter defibrillator (ICD) models. Thirty (26 men, 4 women) patients with ICDs were considered during follow-up. The ICD models were: Telectronics (7), CPI (7), Medtronic (7), Ventritex (5), and Ela Medical (4). All patients were monitored with surface ECG; permanent telemetric endo-ECG monitoring was activated. Then, the effect of two different European telephone systems were tested: TACS system (Sony CM-R111, 2W power) and GSM system (Motorola MG1-4A11, 2 W power). For both systems, the effect during call, reception, active conversation (dialogue), and passive conversation (listening) were observed. Cellular telephones were located first in contact with the programming head, then near the leads system, and lastly, in the hands of the patient. At the end of the evaluations, memories were interrogated again to check for false arrhythmia detections. In five of these patients during arrhythmia induction at device implant (first implant or ICD replacement), we also evaluated possible interference between cellular telephones in the reception phase and the ventricular fibrillation detection phase of the ICD. All evaluated models showed significant noise in the telemetric transmission when the cellular telephone (both TACS and GSM) was located near the ICD and the programming head; noise was particularly significant during call and reception, in most cases leading to loss of telemetry. No false arrhythmia detections have been observed during tests with cellular telephones located on the ICDs. During tests performed with cellular telephones located near the leads or in the hands of patients, no telemetric noises orfalse arrhythmia detections were observed. During induced ventricularfibrillation and cellular telephones in reception mode near the device, the arrhythmia recognition was always correct and not delayed. In conclusion, present ICD models seem to be well protected from electromagnetic interference caused by European cellular telephones (TACS and GSM), without under-/oversensing of ventricular arrhythmias. However, cellular telephones disturb telemetry when located near the programming head. ICD patients should not be advised against the use of cellular telephones, but it has to be avoided during ICD interrogation and programming.

Cost-effectiveness of telephone or surgery asthma reviews: economic analysis of a randomised controlled trial.
BACKGROUND: Only about a third of people with asthma attend an annual review. Clinicians need to identify cost-effective ways to improve access and ensure regular review. AIM: To compare the cost-effectiveness of nurse-led telephone with face-to-face asthma reviews. DESIGN OF STUDY: Cost-effectiveness analysis based on a 3-month randomised controlled trial. SETTING: Four general practices in England. METHOD: Adults due an asthma review were randomised to telephone or face-to-face consultations. Trial nurses recorded proportion reviewed, duration of consultation, and abortive calls/missed appointments. Data on use of healthcare resources were extracted from GP records. Cost-effectiveness was assessed from the health service perspective; sensitivity analyses were based on proportion reviewed and duration of consultation. RESULTS: A total of 278 people with asthma were randomised to surgery (n = 141) or telephone (n = 137) review. Onehundred-and-one (74%) of those with asthma in the telephone group were reviewed versus 68 (48%) in the surgery group (P <0.001). Telephone consultations were significantly shorter (mean duration telephone = 11.19 minutes [standard deviation {SD} = 4.79] versus surgery = 21.87 minutes [SD = 6.85], P <0.001). Total respiratory healthcare costs per patient over 3 months were similar (telephone = pounds sterling 64.49 [SD = 73.33] versus surgery = pounds sterling 59.48 [SD = 66.02], P = 0.55). Total costs of providing 101 telephone versus 68 face-to-face asthma reviews were also similar (telephone = pounds sterling 725.84 versus surgery = pounds sterling 755.70), but mean cost per consultation achieved was lower in the telephone arm (telephone = pounds sterling 7.19 [SD = 2.49] versus surgery = pounds sterling 11.11 [SD = 3.50]; mean difference = - pounds sterling 3.92 [95% confidence interval = - pounds sterling 4.84 to pounds sterling 3.01], P <0.001). CONCLUSIONS: Telephone consultations enable a greater proportion of asthma patients to be reviewed at no additional cost to the health service. This mode of delivering care improves access and reduces cost per consultation achieved.

Telephone consultation and triage: effects on health care use and patient satisfaction.
BACKGROUND: Telephone consultation is the process where calls are received, assessed and managed by giving advice or by referral to a more appropriate service. In recent years there has been a growth in telephone consultation developed, in part, as a response to increased demand for General Practitioner (GP) and Accident and Emergency (A&E) department care. OBJECTIVES: To assess the effects of telephone consultation on safety, service usage and patient satisfaction and to compare telephone consultation by different health care professionals. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials, the specialised register of the Cochrane Effective Practice and Organisation of Care (EPOC) group, Pubmed, EMBASE, CINAHL, SIGLE, and the National Research Register. We checked reference lists of identified studies and review articles and contacted experts in the field. The search was not restricted by language or publication status. SELECTION CRITERIA: Randomised controlled trials (RCTs), controlled studies, controlled before/after studies (CBAs) and interrupted time series (ITSs) of telephone consultation or triage in a general health care setting. Disease specific phone lines were excluded. DATA COLLECTION AND ANALYSIS: Two reviewers independently screened studies for inclusion in the review, extracted data and assessed study quality. Data were collected on adverse events, service usage, cost and patient satisfaction. Due to heterogeneity we did not pool studies in a meta-analysis and instead present a narrative summary of the findings. MAIN RESULTS: Nine studies met our inclusion criteria, five RCTs, one CCT and three ITSs. Six studies compared telephone consultation versus normal care; four by a doctor, one by a nurse and one by a clinic clerk. Three studies compared telephone consultation by different types of health care workers; two compared nurses with doctors and one compared health assistants with doctors or nurses. Three of five studies found a decrease in visits to GP's but two found a significant increase in return consultations. In general at least 50% of calls were handled by telephone advice alone. Seven studies looked at accident and emergency department visits, six showed no difference between the groups and one, of nurse telephone consultation, found an increase in visits. Two studies reported deaths and found no difference between nurse telephone triage and normal care. REVIEWERS' CONCLUSIONS: Telephone consultation appears to reduce the number of surgery contacts and out-of-hours visits by general practitioners. However, questions remain about its affect on service use and further rigorous evaluation is needed with emphasis on service use, safety, cost and patient satisfaction.

The effects of mobile telephoning on driving performance.
The effects of telephoning while driving were studied in three different traffic conditions, i.e. in light traffic on a quiet motorway, in heavy traffic on a four-lane ring-road, and in city traffic. Twelve subjects, unfamiliar with mobile telephones, drove an instrumented vehicle for one hour each day during three weeks and while in each of the three traffic conditions, had to operate the mobile telephone for a short while. To ensure a fixed "heavy traffic load" in the second condition, the subjects were instructed to follow another instrumented vehicle (at a safe distance). The results showed a significant effect of telephoning while driving as opposed to normal driving (i.e., not involving telephone conversation), on the effort subjectively measured by an effort scale and objectively measured by heartrate indices and on some of the measured parameters of driving performance. One half of the subjects had to operate the telephone manually, the other half performed the telephone task with a handsfree mobile telephone set. The subjects who operated the handsfree telephone showed better control over the test vehicle than the subjects who operated the handheld telephone, as measured by the steering wheel movements. Also, a clear improvement over time in the course of the 15 test days was found for some of the measurements. As a consequence of the results, some advice concerning mobile telephoning can be given to authorities, manufacturers, and users.
