Telephone counselling for smoking cessation.

BACKGROUND: Telephone services can provide information and support for smokers. Counselling may be provided proactively or offered reactively to callers to smoking cessation helplines. OBJECTIVES: To evaluate the effect of proactive and reactive telephone support to help smokers quit. SEARCH STRATEGY: We searched the Cochrane Tobacco Addiction Group trials register for studies using free text term 'telephone*' or the keywords 'telephone counselling' or 'Hotlines' or 'Telephone'. Date of the most recent search: August 2000. SELECTION CRITERIA: Randomised or quasi-randomised controlled trials in which proactive or reactive telephone counselling to assist smoking cessation was offered to smokers or recent quitters. DATA COLLECTION AND ANALYSIS: Trials were identified and data extracted by one person and checked by a second. The main outcome measure was abstinence from smoking after at least six months follow-up. We used the most rigorous definition of abstinence in each trial, and biochemically validated rates where available. Participants lost to follow-up were considered to be continuing smokers. Where interventions were similar, we performed meta-analysis using a fixed effects model to give an odds ratio. MAIN RESULTS: Twenty three trials met inclusion criteria. Ten trials compared proactive counselling to a minimal intervention control. There was statistical heterogeneity, with three trials showing a significant benefit, and seven showing non significant differences. Four trials adding telephone support to a face to face intervention control failed to detect a significant effect on long term quit rates. Four trials failed to detect an additional effect of telephone support in users of nicotine replacement therapy. Providing access to a hotline showed a significant benefit in one trial and no significant difference in two. Varying the type of counselling provided has not been shown to affect outcome. REVIEWER'S CONCLUSIONS: Proactive telephone counselling can be effective compared to an intervention without personal contact. There was heterogeneity between trials so the size of effect is uncertain. The available evidence neither confirms nor rules out a benefit of telephone counselling as an adjunct to face to face counselling or pharmacotherapy. Further trials randomising access to helplines are unlikely to be done but indirect evidence suggests they can be a useful part of a smoking cessation service.

Rotavirus vaccine and the news media, 1987-2001.

CONTEXT: In August 1998, the US Food and Drug Administration licensed the first vaccine against rotavirus, the most important cause of severe childhood diarrhea. Fourteen months later, amid intense media activity, the vaccine was withdrawn after an association was found with intussusception. OBJECTIVES: To examine the character of news media stories about rotavirus vaccine before and after intussusception became an issue, to evaluate what prompted the stories, and to assess the extent to which they evoked public reaction. DESIGN AND SETTING: We searched Lexis-Nexis and Video Monitoring Services of America databases for rotavirus vaccine stories from the first US clinical trials (January 1, 1987) until 17 months after withdrawal (March 31, 2001) and examined calls to the National Immunization Hotline during the period in which rotavirus vaccine information was captured (July 1-December 31, 1999). MAIN OUTCOME MEASURES: Mention of vaccine benefits and adverse events, classification of stories as positive, negative, or neutral toward the vaccine, story stimuli, and public response. RESULTS: We included 280 newspaper (primary subject of analysis), 49 wire service, and 257 television stories. Prior to identification of the intussusception association (January 1, 1987-July 14, 1999), 21% of 188 newspaper stories mentioned vaccine adverse events and only 2 stories were negative toward the vaccine. Ninety-nine percent of stories mentioned vaccine benefits. During the period surrounding withdrawal (July 15-December 31, 1999), 93% of 90 stories mentioned adverse events and 77% were negative toward the vaccine. Eighty-four percent mentioned vaccine benefits. The rate of stories per month was 14-fold greater than the preceding period (P<.001); temporal and geographic patterns of media and hotline activity were similar. Thereafter (January 1, 2000-March 31, 2001), only 2 stories focused on rotavirus vaccine. Scientific research or public health actions prompted 80% of stories. Wire service and television stories showed similar patterns. The increase in rotavirus stories in July 1999 was followed by an increase in calls to the National Immunization Hotline regarding rotavirus but not other topics. The number of rotavirus calls that month was 57% higher than for any other childhood vaccine for any month since the hotline began in 1997. Rotavirus calls ceased almost completely after withdrawal of the vaccine in October 1999. CONCLUSIONS: In response to reports about an adverse event, news media stories about vaccines can change abruptly from positivity to negativity. Since most vaccine stories may be stimulated by research and public health actions, opportunities exist to provide the media with accurate information necessary to avoid the "early idealization-sudden condemnation" pattern seen with rotavirus vaccine.

Epidemiologic study of cats and dogs affected by the 1991 Oakland fire.

OBJECTIVE: To identify risk factors of pets affected by the 1991 Oakland, Calif fire for being lost, found, adopted, or reunited with owners. DESIGN: Retrospective cohort study. ANIMALS: 1,075 cats and 197 dogs affected by the fire and 221 cats and 128 dogs not affected by the fire. PROCEDURES: Records compiled from 1991 to 1995 by the Oakland Firestorm Pet Hotline were analyzed. RESULTS: Peak activity for the hotline was on days 3 and 4 after the fire, but decreased to a low, steady rate by day 21. Many pets were found that had been abandoned or were part of a large free-roaming population that existed at the time of the fire. Many were missing after the fire and presumed killed. The longer owners delayed looking for their pet, the lower the chance of being reunited. Pets wearing collars with the owners' names and addresses had a more than 10-fold chance of being reunited, compared with pets without collars. Increasing odds for adoption of lost pets was associated with their proximity to the fire. CLINICAL IMPLICATIONS: Hotlines set up after sudden impact disasters, such as the Oakland Firestorm Pet Hotline, will probably register primarily abandoned animals. Reunion of pets with their owners appears to be most likely for those that receive an overall better level of care than pets found at other times. Adoption of pets after this disaster was primarily by the person who found that animal and principally resulted when the pet was found close to the disaster area.

Simulated clinical evaluation of conventional and newer fluid-warming devices.

The purpose of the study was to evaluate the ability of five commercially available devices utilizing a variety of heat exchange technologies to deliver normothermic (37 degrees C) fluids. Conditions of slow (6.5 mL/ min), moderate (13-25 mL/min), and rapid (gravity and pressure driven flows, roller clamp wide open) infusion were simulated. Fluid temperatures were measured using rapid response thermistors after the fluid exited the heat exchanger (T outlet) and before delivery to the patient intravenously (IV) (T distal). Devices tested were the FW537, H1000, Hotline, BairHugger, and Flotem IIe. Fluids tested were crystalloid at room temperature and red cells diluted with saline (11-19 degrees C). At slow and moderate flows, T distal of crystalloid was between 35.3 and 37.9 degrees C for Hotline at 42 degrees C, 33.8 and 37.7 degrees C for H1000 at 42 degrees C, 29.4 and 34.2 degrees C for BairHugger, 26.1 and 31.5 for Flotem IIe, and 23.8 and 32.1 for FW537 at 42 degrees C. With gravity and pressure driven flows, T distal of crystalloid were 39.0 and 38.9 for H1000 at 42 degrees C, 38.7 and 38.4 degrees C for FW537 at 42 degrees C, 34.7 and 28.9 degrees C for Hotline at 42 degrees C, 29.2 and 24.2 degrees C for BairHugger, and 29.7 and 24.2 degrees C for Flotem. In conclusion, only the H1000 at 42 degrees C was effective at delivering normothermic fluids at all clinically relevant flow rates. The Hotline at 42 degrees C was effective at slow and moderate flow, whereas the FW537 was effective only at rapid flow.

Evaluation of a new fluid warmer effective at low to moderate flow rates.

BACKGROUND: The tendency of intravenous fluid exiting the heat exchanger of a fluid warmer to cool to room temperature increases as the rate of infusion slows and the length of tubing between the heat exchanger and the patient increases. Thus, slow to moderate flow rates result in the delivery of fluid near room temperature despite the use of a fluid warmer. The volumes infused even at low flow rates may be large relative to the size of infants and children and may result in a significant decrease in patient temperature. METHODS: A new warmer (Hotline, Level 1 Technologies) that actively heats the fluid in the delivery tubing was evaluated and compared to two different conventional dry-wall warmers: the model DW1000A (Baxter Health Care) and the FloTem IIe (DataChem). Cold blood (4-10 degrees C) and room temperature saline (22 degrees C) were pumped through the warmers and the delivered temperature was measured as the flow rate was varied from 50 to 12,000 ml/h. RESULTS: The Hotline was more effective than the Baxter or the FloTem IIe at flow rates between 50 and 6,000 ml/h for saline and at flow rates between 50 and 3,000 ml/h for blood. Insulating the tubing beyond the heat exchangers of the conventional warmers improved their performance, but the delivered temperatures were still less than those of the Hotline at low flow rates. CONCLUSIONS: The Hotline is more effective than conventional warmers at slow flow rates, and may be useful for preventing hypothermia when large volumes of fluid relative to patient size are infused at slow rates.

Evaluation of a media campaign to increase knowledge about emergency contraception.

Our objective was to evaluate a media campaign designed to increase knowledge about emergency contraception. Random telephone surveys were conducted before and after the campaign to measure changes in knowledge about emergency contraception. Change in the volume of calls to the Emergency Contraception Hotline (1-888-NOT-2-LATE) was a secondary measure of impact. Significant increases occurred in the proportions of women who knew that something could be done after intercourse to prevent pregnancy, who knew the term emergency contraception, who knew of the 72-h time limit, and who had heard of the Hotline. In addition, the number of calls to the Hotline increased substantially. A public education media campaign resulted in significant increases in knowledge about emergency contraception. The first contraception advertisement ever shown on television did not provoke controversy.

Access to emergency contraception.

OBJECTIVE: To evaluate access to emergency contraception among women seeking help from clinicians who registered to be listed on the Emergency Contraception Hotline (1-888-NOT-2-LATE, ie, 1-888-668-2528) and the Emergency Contraception Website (not-2-late.com). METHODS: Two college-educated investigators posing as women who had a condom break the previous night called 200 providers to seek help. RESULTS: Only 76% of attempts resulted in an appointment or telephone prescription from a hotline provider within 72 hours, 14% were failures, and 11% resulted in referrals to other providers not listed on the hotline or website. CONCLUSION: Even under ideal conditions, access to emergency contraception is currently constrained. Although emergency contraception could reduce significantly the incidence of unintended pregnancy and the consequent need for abortion, its potential will not be realized unless women have better access to clinicians who can prescribe emergency contraceptive pills.

[Socioepidemic analysis of sources of information and medical care for a subpopulation of female and male participants in a nationwide informative campaign in Germany on "Danger Signal: Heartburn"].

Whilst the prevalence of gastroesophageal reflux is increasing, most people are unaware of its possible consequences. Therefore, in Autumn 2000 a nationwide information campaign was launched on the symptoms of gastroesophageal reflux and its possible treatments. One part of the information campaign was a telephone hotline which was followed by an interview by phone or a mailed questionnaire. The objective of this was to find out more about the people concerned and their complaints. The subjects of both data sets were on average 53 respectively 57 years old, half of them were female and over 60 % had had heartburn for more than two years. The interview showed that 53 % took notice of the hotline by a press release. The interviewed persons gathered information in general about health-related issues primarily from newspapers and TV reports and from their physician. 81.7 % of the questionnaire sample had already at least one gastroscopy. Another 9.5 % made use of medical services because of their complaints in the last year. 8.8 % used exclusively over-the-counter medication for relief from their complaints. These three groups of different degrees of utilisation differed in respect of age, intensity and duration of the symptom heartburn and lifestyle-factors such as smoking. Those who had a gastroscopy were older, symptoms were more prolonged, more severe, more often and comprised a wider range of symptoms and less cigarette consumption. The analysis of both samples showed that the telephone hotline was used mainly by people who had had their symptoms for a long time and had already been in medical care. The chosen means of information stated by the sample indicate that media are prominently involved in disseminating information and educating the public.

[Three years of vertical networking in the German Network of Competence on Viral Hepatitis: what can we learn from the usage of different information tools?].

Treatment of patients with viral hepatitis is time-consuming and sometimes complicated. Several sources of information have been established as internet sites, however systematic analyses of the need and use of these information platforms are lacking. The Competence Network on Viral Hepatitis (Hep-Net) was established in 2002 and offers a telephone hotline, an e-mail service and a home page with frequently asked questions (FAQs). On the internet pages "FAQs" 38 125 hits have been registered on single "question-answer-units" within three years. In a half of the cases the question are associated with modes of transmission. In contrast, patient's questions in e-mail and the telephone hotline are mainly dealing with the treatment of hepatitis C. More than 46 % of the physician's questions referred to unclearness in indications for treatment. Questions on specific medical problems of individual patients and, in e-mail, also on legal issues played a major part. Many of these questions have not been addressed in the actual guidelines in Germany. In summary, the Hep-Net vertical networking tools represent a fast, quality-assured endorsement to the daily management of patients with viral hepatitis. The combination of internet, e-mail service and telephone hotline gives consideration to individual necessities of patients and physicians. However, the detailed analysis of usage also shows limitations of current guidelines which should be considered during updating.

Multiple sclerosis pathways: an innovative nursing role in disease management.

Multiple sclerosis (MS), a chronic disease of the central nervous system, is characterized by a variable and unpredictable course. The most common pattern of the disease is the relapsing-remitting form in which clearly defined relapses (also called exacerbations) are followed by complete or incomplete recovery. Interferon beta-1b (Betaseron), a drug that affects the natural course of the disease, was developed for the treatment of relapsing-remitting MS. Multiple Sclerosis Pathways (MSP), a disease management program, was developed to provide comprehensive and personal support to MS patients taking interferon beta-1b and to serve as an information resource for all people with MS, their families, and healthcare professionals. The MSP program includes personal patient assistance, reimbursement services, a 24-hour nurse hotline, training program, educational resources, and injection supplies. The nurse hotline counselor (NHC) utilizes the nursing process in a unique telephone nursing practice in this program. The positive impact of education and support on adherence to therapy has been validated by training and nurse hotline data.

Nicotine replacement therapy in a group model HMO.

OBJECTIVE: To examine patient response to a smoking cessation program that combined a nicotine replacement system (patch) with telephone support. DESIGN: Randomized trial. SETTING: A large Midwestern HMO. PARTICIPANTS. Five hundred and nine smokers who attended orientation sessions where an overview of the study and the use of the nicotine patch was presented. INTERVENTION: All subjects received a prescription for a nicotine replacement patch (Prostep, Lederle Laboratories, Wayne, NJ). Participants were randomly assigned to one of three intervention groups. Group I participants (n = 166) received no additional support. Group II participants (n = 167) were registered with a 24-hour telephone hotline. Group III participants (n = 167) were registered with the 24-hour telephone hotline and received four follow-up telephone calls from health educators. OUTCOME MEASURE: The primary outcome measure was smoking cessation. Subject satisfaction with study components was also evaluated. RESULTS: Overall, there was no significant difference by group in smoking cessation rates: 20% of patients in all three groups were smoke-free after 12 months. Few patients (1%) used the telephone hotline. The telephone follow-up did not have an impact on cessation rates, and most patients (92%) reported that the orientation session was useful. CONCLUSIONS: The study experience has helped the HMO evaluate various study components and has had an impact on currently used telephone intervention strategies and educational materials.

EPA's control technology approach to assisting states and regions with air toxics problems: five case studies.

The Environmental Protection Agency (EPA) announced in June 1985 a new strategy to reduce public exposure to toxic air pollutants in the ambient air. Over the next 5-8 years, the strategy called for State and Local authorities to take on more of the lead regulatory role, with the Agency providing technical and financial assistance to their efforts. The shift in emphasis and responsibility from the Federal level to State and Local air toxics programs and the need to transfer expertise from the Federal level to the appropriate State or Local level prompted EPA's Office of Research and Development (ORD) and EPA's Office of Air Quality Planning and Standards (OAQPS) to develop and implement an innovative technical assistance program. This program is called the Control Technology Center (CTC). It has since been expanded to include technical assistance in the area of control of air toxics, particulate matter, and volatile organic compounds (VOCs); emission measurements; and other areas where expertise is available to ORD and OAQPS. During the CTC's first year of operation, operating guidelines were developed and three categories of technical assistance were established. These categories are telephone HOTLINE calls, direct engineering assistance, and technical guidance projects. The CTC HOTLINE is a special telephone number which State and Local Agencies can call for easy access to EPA personnel who can provide prompt assistance in a variety of ways including discussions, references to pertinent literature, and referrals to other EPA personnel. In some cases, a HOTLINE call will require more in-depth engineering analysis indicating a need for direct engineering assistance. These projects tend to be short-term (2 to 3 months) and specific in nature. In some cases, several agencies may indicate a need for information on the same source, or a group of Agencies may make a joint request. In these cases, the CTC Steering Committee, a group who advises the CTC managers, may decide that a technical guidance project is indicated. Technical guidance projects are longer-term and are intended to be of broad interest, useful to many agencies. This paper discusses the development of the CTC, experience to date with its operation, and future plans. In addition, five CTC projects are discussed to illustrate the assistance provided.

Self-help interventions for smoking cessation.

BACKGROUND: Many smokers give up smoking on their own, but provision of materials giving advice and information may assist them and increase the number who quit successfully. OBJECTIVES: The aims of this review were to determine the effectiveness of different forms of self-help materials, compared with no treatment and with other minimal contact strategies; the effectiveness of adjuncts to self-help, such as computer generated feedback, telephone hotlines and pharmacotherapy; and the effectiveness of approaches tailored to the individual compared with non-tailored materials. SEARCH STRATEGY: We searched the Cochrane Tobacco Addiction Group trials register. Date of the most recent search September 1999. SELECTION CRITERIA: We included randomised trials of smoking cessation with follow-up of at least six months, where at least one arm tested a self-help intervention. We defined self-help as structured programming for smokers trying to quit without intensive contact with a therapist. DATA COLLECTION AND ANALYSIS: We extracted data in duplicate on the type of subjects, the nature of the self-help materials, the amount of face to face contact given to subjects and to controls, outcome measures, method of randomisation, and completeness of follow-up. The main outcome measure was abstinence from smoking after at least six months follow-up in patients smoking at baseline. We used the most rigorous definition of abstinence in each trial, and biochemically validated rates when available. Where appropriate, we performed meta-analysis using a fixed effects model. MAIN RESULTS: We identified forty-five trials. Twenty seven compared self-help materials to no intervention or tested materials as an adjunct to advice. In nine trials in which self-help was compared to no intervention there was a pooled effect which just reached statistical significance (odds ratio 1.23, 95% confidence interval 1.02 to 1.49). There was no evidence of benefit from adding self-help materials to face to face advice, or to nicotine replacement therapy. There was evidence from eight trials using materials which were tailored for the characteristics of individual smokers that such personalised materials were more effective than standard materials (odds ratio 1.41, 95% confidence interval 1.14 to 1.75). Adding follow-up telephone calls from counsellors also appeared to increase quitting (odds ratio 1.62, 95% confidence interval 1.33 to 1.97). One trial of offering access to a hotline also showed an effect. REVIEWER'S CONCLUSIONS: Self-help materials may provide a small increase in quitting compared to no intervention. There is no evidence that they have an additional benefit over other minimal interventions such as advice from a health care professional, or nicotine replacement therapy. There is evidence that materials tailored for individual smokers are more effective.

Effectiveness of altered incentives in a food safety inspection program.

BACKGROUND: The Los Angeles County Department of Health Services revamped its retail food establishment inspection program in 1998 to include, among other novel provisions, the prominent posting of grades. The purpose of the present study is to examine results from the second year of the revamped program to determine the longer-term impact of the program. METHODS: An analysis of program results for Year 1 led to several program refinements: stratification of risk categories, certification of food handlers, and an external fraud hotline. Outcome measures used included routine inspection scores; closure rates; scores from owner-initiated inspections and departmentally initiated inspections; inspection frequencies; compliance with food handler certification requirements; and frequency of use of the external fraud hotline. RESULTS: Inspection scores continued to increase in 1999, while the rate of closures decreased. The owner-initiated inspections also resulted in improved scores, generally maintained on subsequent inspections. Higher risk establishments were inspected more frequently than were lower risk establishments. Over 30,000 food handlers were certified. The external fraud hotline received 16 fraud complaints. CONCLUSIONS: Results indicate that retail food establishments are taking stronger action to assure compliance with food safety practices.

Evaluation of crisis intervention services with anonymous clients.

A technique is introduced for using intake data to evaluate crisis intervention services in which client anonymity prevents the usual follow-up procedures. The technique is based on the assumptions (a) that the rate of reuse of the service indicates the effectiveness of the service, and (b) that counselors' estimates of their effectiveness provide some indication of the adequacy of their training. The study was conducted at a 24-hour metropolitan hotline. In addition to obtaining the usual intake information, counselors asked callers how often they had used the hotline previously and then rated their own effectiveness in aiding the callers. Analyses show the relative effectiveness of the hotline with various types of callers and problems and suggest areas where additional counselor training is desirable.

Population-level intervention to promote chlamydia screening. Moving toward implementation of chlamydia hedis 2000 measure

Background: HEDIS 2000 measure includes chlamydia screening in women which is designed to assess the percentage of sexually active women 15 to 25 years who have received at least one screening test for chlamydia during the reporting year. This study is being undertaken to determine feasibility of implementing a population-level intervention within HMOs to promote chlamydia screening. This abstract presents preliminary findings from the Birmingham project of this multicenter study.Methods: In partnerships with two HMOs, series of outreach methods were used in a stepwise fashion to determine potential barriers and enabling factors for the implementation of chlamydia HEDIS measure in a conservative social environment. Mail outreach was sequentially combined with newspaper, TV, radio advertisements and poster displays. Both qualitative and quantitative impact of the outreach efforts were measured across the timeline. The measures included reporting for chlamydia screening (urine LCR) and infection rate, monitoring chlamydia hotline and staffed phoneline use, and assessment of untoward effects and cost-analysis of the chlamydia outreach campaign.Results: The key findings are: the benefit of chlamydia screening is not understood by general public, letters send by Health Plans to their members are not read by many subscribers, and there are wide gaps between adolescents and their parents, in knowledge, attitudes, beliefs in regard to obtaining information and accessing the screening services (teens prefer hotline, brochure in an envelop addressed to teens, incentives for reporting to the clinic for screening, vs. parents prefer staffed phone consults, "exposed" brochure addressed to parents, and no incentives). A month of sustained and repeat multi-media campaign resulted in 330 hotline calls, 83 phone calls and only 17 subjects being tested (3 were positive) though many more intended to come. Cumulative effects and cost of various outreach efforts are being monitored. Informational chlamydia brochures and free test cards mailed to the homes generated no negative response from the subscribers, contrary to the concerns of the HMOs. Conclusion: To be effective, investment in public education campaign and social marketing strategies must be integrated in population-level intervention for the implementation of the chlamydia HEDIS 2000 measure.

[Heating capabilities of fluid warming systems during low infusion rates].

OBJECTIVE: The aim of the study was to compare the effects of different fluid warming systems on their heating capabilities during low infusion rates. METHODS: Heating capabilities of four different fluid warming systems and their capabilities to warm fluids with 20 +/- 0.5 degrees C above 32 degrees C were measured: 1) Hotline(R) Fluid Warmer, 2) Gymar, using three disposable tubing systems - "Pediatric", "Standard", and "High-Flow", 3) Astotherm, and 4) Astotherm plus 260. Low to moderate infusion rates (100, 300, 600, and 900 ml/h) were achieved using motor pumps. Infusate temperatures were measured at 17 degrees C and 20 degrees C room temperature at the distal end of the disposable tubing. Statistical analysis was performed using a computer based program (NCSS). Differences between the groups were analysed by the unpaired Wilcoxon Test. Significance was defined with a p < 0.05. RESULTS: During low to moderate infusion rates (100 - 900 ml/h), infusate temperatures of > 32 degrees C were attained only by the Hotline-device in a reliable manner independent of the applied room temperature. The devices Astotherm plus 260 und Astotherm attained these temperatures during infusion rates of 300 ml/h and 600 ml/h respectively. Final temperatures of > 32 degrees C were maintained by Gymar during infusion rates of 600 ml/h, when the disposable tubing system "Pediatric" was used. Using the same device but different tubing systems, final temperatures of >32 degrees C were attained during 900 ml/h ("Standard") or failed ("High-Flow"). With all devices, increasing the room temperature by 3 degrees C was followed by higher infusate temperatures, which were more pronounced in those devices without disposable tubing warming (p < 0.01). CONCLUSION: In this laboratory investigation, Hotline performance was superior with respect to providing final temperatures > 32 degrees C during low to moderate infusion rates. Astotherm Plus 260 seems to be an alternative cost effective device in case of infusion rates of more than 300 ml/h.

Simulated clinical evaluation of four fluid warming devices*.

The fluid warming capabilities of the Bair Hugger, Hotline, Standard Ranger and Fluido devices were evaluated in the laboratory with gravity flow via a 14G cannula (1 m head of fluid) and with the fluid bag pressurised to 300 mmHg. The resulting flows (70-450 ml.min(-1)) were recorded. At a room temperature of 22 degrees C, no device warmed the fluid to 37 degrees C. However, the Standard Ranger with gravity flow and the Fluido with both gravity and pressurised flow achieved 35 degrees C, whereas the Bair Hugger and Hotline with both gravity and pressurised flow, and the Standard Ranger with pressurised flow, achieved only 24-31 degrees C. However, from the way delivered temperatures changed with flow, we calculated that all four devices would achieve close to 37 degrees C at the flows specified by the manufacturers: 17, 83, 150 and 800 ml.min(-1) for the Bair Hugger, Hotline, Standard Ranger and Fluido, respectively.
