Effects of audio and visual distraction on patients' vital signs and tolerance during esophagogastroduodenoscopy: a randomized controlled trial.

BACKGROUND: Esophagogastroduodenoscopy (EGD) provides an indispensable and unambiguous inspection allowing the discovery upper gastrointestinal lesions. However, many patients are anxious about undergoing EGD. Few studies have investigated the influence on patients' vital signs and tolerance during EGD using subjective and objective assessments. This study was a prospective randomized controlled study that investigated the influence of audio and visual distraction on EGD. METHODS: We randomly divided 289 subjects who underwent EGD into 4 groups (control group, audio group, visual group, combination group) and examined their vital signs, heart rate variability (HRV), psychological items, and acceptance of distraction. RESULTS: Pulse rate (PR) at post-distraction and post-EGD in the 3 distraction groups were significantly lower than those of control group (p <  0.001 and p <  0.01, respectively). Blood pressure (BP) during and post-EGD was significantly higher than that at pre-EGD in control group (p <  0.05), but no significant elevation of BP was observed during the latter half of EGD and post-EGD in the 3 distraction groups. BP at post-distraction improved significantly compared to pre-distraction in the 3 distraction groups (p <  0.05). There was a significant difference in the low-frequency (LF) power/ high-frequency (HF) power at post-distraction and post-EGD among the 4 groups (p <  0.001 and p <  0.001, respectively). The LF power/HF power at post-distraction and post-EGD in the 3 distraction groups was significantly lower than that in control group (p <  0.05). Several items of profile of mood states (POMS) and the impression of EGD at post-distraction improved significantly compared to those at pre-distraction among the 3 distraction groups (p <  0.05). Visual analog scale (VAS) of willingness for the next use of distraction in the 3 distraction groups was excellent because VAS was more than 70. CONCLUSIONS: Distractions effectively improved psychological factors, vital signs and some of HRV at pre and post-EGD. Distractions may suppress BP elevation during the latter half of EGD and lead to stability of HRV on EGD. TRIAL REGISTRATION: This prospective trial was registered in the University Hospital Medical Information Network (UMIN) Clinical Trials Registry as UMIN000029637. Registered on 20 October 2017.

Pre-endoscopic tachycardia predicts increased sedation dose and lower adenoma detection rate in patients undergoing endoscopic procedures: a case control study.

BACKGROUND: Tachycardia prior to endoscopic procedures is commonly encountered which reflect patient anxiety status. Despite this frequent occurrence, it is unclear if in a patient with tachycardia sedation dose should be modified. The aim of our study was to assess the effect of pre-endoscopic tachycardia on sedation dose. METHODS: A retrospective analysis of all patients who underwent upper endoscopy and colonoscopy at EMMS Nazareth hospital were performed. We excluded patients with diseases and medications affecting the heart rate. RESULTS: A total of 2855 patients were included in the study. Two-hundred and thirty-seven patients had tachycardia before endoscopy (8.3%, group A) as compared to 2618 (group B) patients who had heart rate ≤100 beats per minute. The mean dosage of propofol in group A was significantly higher (62.6±33.2 mg vs. 57.4±29.9 mg) than in group B (P=0.01). There was no difference in the cecal intubation rate among the two groups (P=0.9). Notably, the adenoma detection rate was significantly lower among group A patients as compared to group B (13.6% vs. 22.8%, P=0.02) patients. There were no sedation related complications. CONCLUSIONS: Tachycardia prior to endoscopic procedures was associated with higher sedative dosage and lower adenoma detection rate, however no major complications were recorded. These data should be taken into consideration to optimize procedure quality.

Preparatory information reduces gastroscopy-related stress in children as confirmed by salivary cortisol.

BACKGROUND/AIMS: This study aimed to determine whether the anxiety levels of pediatric patients who undergo endoscopy are reduced after receiving preparatory information about the endoscopic procedure by monitoring their salivary cortisol (s-cortisol) levels. PATIENTS AND METHODS: A total of 184 children undergoing gastroscopy under sedoanalgesia were included in the study. All the patients received a brief explanation of the endoscopic procedure. Patients were divided into two groups; Group Unexplained did not receive any further information other than a brief explanation of the procedure, Group Explained received more detailed explanation of the procedure. To determine anxiety levels, saliva specimens were taken on the day before the procedure to examine cortisol levels before and after endoscopy. Anxiety scores before endoscopy were calculated by the modified Yale Preoperative Anxiety Scale. Patients were monitored throughout sedoanalgesia, including during the endoscopy, sedation and recovery, and total propofol dosages were recorded. RESULTS: Eighty-nine children undergoing gastroscopy (age 11.55 ± 2.52 years; 50.5% girls) constituted Group Explained and 95 children undergoing gastroscopy (age 11.44 ± 2.66 years; 56.8% male) constituted Group Unexplained. The anxiety score, duration of sedation, endoscopy and recovery, propofol dose, pre- and post-endoscopy s-cortisol levels were significantly reduced in Group Explained. CONCLUSIONS: We demonstrated that when endoscopic procedure is explained broadly to a child, the procedural stress is significantly less, as measured by the s-cortisol levels and the anxiety questionnaire. It is important for the attending physician to explain all aspects of examination carefully.

Effect of Information of Patients' Coping Style on Pregastroscopy Anxiety.

Examination of the relationship between patients' coping style, pregastroscopy information, and anxiety associated with gastroscopy in China was the aim of this study. A pretest, post-test, nonrandom assignment study with a two by two design was conducted. One hundred forty-five patients who underwent initial gastroscopy without sedation were classified into 2 groups on the basis of the coping style: information seekers or information avoiders using the Information Subscale of the Krantz Health Opinion Survey (KHOS-I). All participants were given standardized procedural information about gastroscopy as routine care. Half of each group was assigned to receive additional sensory information describing what sensation they would experience and how to cooperate to alleviate the discomfort. State anxiety assessed by the State Anxiety Scale of Spielberg's State-Trait Anxiety Inventory, blood pressure, and pulse were measured at enrollment and before gastroscopy. The information seekers and avoiders who received additional sensory information experienced significantly less state anxiety after the intervention. In contrast, the information seekers and avoiders who received standardized procedural information maintained their preintervention state anxiety level. Most patients reported their preference for sensory information. In conclusion, the provision of sensory information could significantly reduce patients' pregastroscopy anxiety regardless of patients' information coping style.

Ultrathin unsedated transnasal gastroscopy in monitoring eosinophilic esophagitis.

BACKGROUND: Ultrathin unsedated transnasal gastroscopy (UTEG) has a number of advantages applicable to eosinophilic esophagitis (EoE) and has not been evaluated for this condition. AIM: The aim of the study is to determine the feasibility of UTEG in patients with EoE and the acceptability of histological specimens obtained at biopsy. METHOD: All patients with a diagnosis of EoE presenting to the outpatients department of two hospitals (Box Hill Hospital and The Alfred Hospital, Melbourne Australia) were asked to participate in the study. UTEG was performed on consenting individuals. Feasibility was determined by the success of nasal intubaton, patient perception according to post procedural survey, and adequacy of esophageal biopsies was assessed. RESULTS: Ninety-six consecutive patients with EoE were offered UTEG, and 24 agreed to participate in the study. Seventy-four UTEGs were performed over a period of 26 months (September 2012 to December 2014). Nineteen patients had repeat procedures. Successful nasal intubation occurred in 97% (72 of 74 procedures), and 21 of 24 (86%) described high satisfaction with the procedure and minimal discomfort, and would choose UTEG for future procedures. Mean duration was 5 min. Adverse events of epistaxis (three cases) and vomiting of liquid contents during the procedure (two cases) were recorded, cardiorespiratory parameters remaining normal in all patients. All completed procedures produced adequate histological samples. CONCLUSION: In those who decide to undergo UTEG, it is a safe and well-tolerated procedure.

Usefulness of a fast track list for anxious patients in a upper GI endoscopy.

BACKGROUND: To determine whether patients with no alarm signs who ask the endoscopist to shorten their waiting time due to test result anxiety, represent a risk category for a major organic pathology. METHODS: At our open-access endoscopy service, we set up an expedite list for six months for outpatients who complained that the waiting time for gastroscopy was too long. Over this period we studied 373 gastroscopy patients. In addition to personal details, we collected information on the presence of Hp infection and compliance with dyspepsia guideline indications for gastroscopy. RESULTS: Average waiting time was 38.2 days (SD 12.7). The 66 patients who considered the waiting time too long underwent gastroscopy within 15 days. We made 5 diagnoses of esophageal and gastric tumour and gastric ulcer (7.6%) among the expedite list patients and 14 (4.6%) among those on the normal list (p=0.31). On including duodenal peptic disease in the analysis, the total prevalence rate rose to 19.7% in the short-wait group and to 10.4% (p=0.036) in the longer-wait group. DISCUSSION AND CONCLUSIONS: Our data suggests that asking to be fast-tracked does not have prognostic impact on the diagnosis of a major (gastric ulcer and cancer) pathology.

Patients' perspectives of living with a percutaneous endoscopic gastrostomy (PEG).

BACKGROUND: Since enteral nutrition therapy is the preferred nutritional support for dysphagic patients with a range of diagnoses, PEG has become part of traditional care. However, enteral nutrition with PEG transfers treatment responsibility and activity to the patients and their carers, so the advantages should be discussed. The aim of this study was therefore to investigate patients' experience of living with a percutaneous endoscopic gastrostomy (PEG) in order to increase the understanding of patients' need for support. METHOD: In a prospective study at Karolinska University Hospital in Sweden, data were collected consecutively at the time of PEG and two months later using a study-specific questionnaire about each patient's experience of living with a PEG. Fishers exact test was used to test for statistically significant difference at five per cent level. RESULTS: There were 104 responders (response rate of 70%). Women felt more limited in daily activity compared to men (p = 0.004). Older patients experienced a more limited ability to influence the number of feeding times compared to younger (p = 0.026). Highly educated patients found feeding more time-consuming (p = 0.004). Patients with a cancer diagnosis reported that the PEG feeding interfered with their oral feeding more than patients with a neurological disease (p = 0.009). Patients mostly contacted the PEG outpatient clinic with problems regarding their PEG, and were mainly assisted by their spouse rather than district nurses. CONCLUSIONS: PEG feeding is time-consuming and interferes with daily life. Although 73% was satisfied, patients' experiences of living with a PEG may be dependent on age, sex, education and diagnosis. Spouses are the main carers for PEG patients at home, and patients prefer to go to the PEG outpatient clinic for help if problems occur.

The effectiveness of clinical hypnosis in the digestive endoscopy: a multiple case report.

The aim of this study is to evaluate the efficacy and viability of hypnosis before and during a gastrointestinal endoscopy. Six Gastroscopies and 22 colonoscopies were carried out under hypnosis in a group of patients. The patients ranged in age from 20 and 67 years and have a history of previously incomplete and poorly tolerated examinations or expressed an active demand for sedation. For 6 of the patients who underwent a gastroscopy under hypnosis, the procedure was successfully completed, reaching the second part of the duodenum without difficulty for the endoscopist. Colonoscopy of the cecum was completed in 19 of 20 patients. All patients, except 1, considered their tolerance level as "good." Hypnosis facilitated an adequate endoscopy intervention without any discomfort in 85% of the cases examined. Avoidance of anaesthesia reduces risk to the patient. Hence, hypnosis for gastrointestinal endoscopy appears to provide a promising strategy.

Acceptability and accuracy of a non-endoscopic screening test for Barrett's oesophagus in primary care: cohort study.

OBJECTIVES: To determine the accuracy and acceptability to patients of non-endoscopic screening for Barrett's oesophagus, using an ingestible oesophageal sampling device (Cytosponge) coupled with immunocytochemisty for trefoil factor 3. DESIGN: Prospective cohort study. SETTING: 12 UK general practices, with gastroscopies carried out in one hospital endoscopy unit. PARTICIPANTS: 504 of 2696 eligible patients (18.7%) aged 50 to 70 years with a previous prescription for an acid suppressant (H(2) receptor antagonist or proton pump inhibitor) for more than three months in the past five years. MAIN OUTCOME MEASURES: Sensitivity and specificity estimates for detecting Barrett's oesophagus compared with gastroscopy as the ideal method, and patient anxiety (short form Spielberger state trait anxiety inventory, impact of events scale) and acceptability (visual analogue scale) of the test. RESULTS: 501 of 504 (99%) participants (median age 62, male to female ratio 1:1.2) successfully swallowed the Cytosponge. No serious adverse events occurred. In total, 3.0% (15/501) had an endoscopic diagnosis of Barrett's oesophagus (≥1 cm circumferential length, median circumferential and maximal length of 2 cm and 5 cm, respectively) with intestinal metaplasia. Compared with gastroscopy the sensitivity and specificity of the test was 73.3% (95% confidence interval 44.9% to 92.2%) and 93.8% (91.3% to 95.8%) for 1 cm or more circumferential length and 90.0% (55.5% to 99.7%) and 93.5% (90.9% to 95.5%) for clinically relevant segments of 2 cm or more. Most participants (355/496, 82%, 95% confidence interval 78.9% to 85.1%) reported low levels of anxiety before the test, and scores remained within normal limits at follow-up. Less than 4.5% (2.8% to 6.1%) of participants reported psychological distress a week after the procedure. CONCLUSIONS: The performance of the Cytosponge test was promising and the procedure was well tolerated. These data bring screening for Barrett's oesophagus into the realm of possibility. Further evaluation is recommended.

Assessment of anxiety levels in patients during elective upper gastrointestinal endoscopy and colonoscopy.

BACKGROUND/AIMS: Upper gastrointestinal endoscopy and colonoscopy are frequently performed procedures that can cause anxiety related to disappointing expectations, embarrassment and fear of discomfort. The aim of this study was to examine the possible relationship between state anxiety and trait anxiety with upper gastrointestinal endoscopy and colonoscopy. METHODS: Ninety-eight consecutive outpatients (52 gastroscopy and 46 colonoscopy) undergoing upper gastrointestinal endoscopy and colonoscopy were interviewed to evaluate anxiety. Anxiety was rated at baseline and immediately prior to upper gastrointestinal endoscopy and colonoscopy using the Spielberger State- Trait Anxiety Inventory. RESULTS: A modest but significant increase was detected in state anxiety prior to upper gastrointestinal endoscopy and colonoscopy but no change was detected in trait anxiety in either group. Anxiety levels were not related with the type of endoscopic procedure. State anxiety scores increased from 36.9 (28.5 42.5) to 45.7 (27.5 48.0) (p=0.001) in patients undergoing upper gastrointestinal endoscopy and from 36.2 (26.5 38.5) to 44.8 (30.5 48.0) (p=0.001) in patients undergoing colonoscopy. Females had higher anxiety levels than males in both groups. CONCLUSIONS: Diagnostic outpatient upper gastrointestinal endoscopy and colonoscopy were associated with remarkable anxiety in patients; however, anxiety levels were not related with the type of endoscopic procedure.

Long-term percutaneous endoscopic gastrostomy feeding in young adults with multiple disabilities.

AIM: To study the outcomes from initiation of percutaneous endoscopic gastrostomy (PEG) feeding in young people with profound multiple disabilities. METHODS: Observations were made on 40 adults with lifelong intellectual disability (mental retardation) and quadriplegia, in whom PEG feeding was initiated during 1990-2008. There were 20 men and 20 women aged 15-40 years at the time of the audit, living in settings with 24 h registered nurse staffing. RESULTS: Undernutrition and recurrent aspiration with frequent infections were cited as reasons for PEG feeding. The positive outcomes were that some were said to be more alert for a time following the procedure; and these young adults lived with PEG feeding for an average of 8.5 years, some up to 18 years. In that time, however, they all experienced complications of the PEG insertion, and of the PEG feeding process. There were no measurable improvements in cognition. There were no reductions in prescription of medications. They all required frequent daily interventions by nurses to maintain medical stability. Ten people died during this review period, from continued deterioration in neurological status, with pneumonia cited as the terminal event. CONCLUSIONS: Unlike other people with neurological deterioration, young adults with lifelong multiple disabilities may live for many years with PEG feeding. There is little gain in quality of life.

Clinical trial: music reduces anxiety levels in patients attending for endoscopy.

BACKGROUND: Patients attending for endoscopy are generally anxious and worried. AIMS: To examine whether music reduced anxiety levels in patients attending for endoscopic procedures. METHODS: Prospective randomized controlled trial of 180 patients (M:F 81:99). The effect of age (< or = or >51 years) and procedure (gastroscopy or flexible sigmoidoscopy/colonoscopy) on anxiety levels (state-trait anxiety inventory) on arrival in the unit and immediately before the endoscopy procedure, after listening to music or no music (control group) for the same period. RESULTS: At baseline, anxiety levels were not influenced by age (< or =51 years, n = 56:42.21 +/- 9.18; >51 years, n = 124:39.99 +/- 10.13 (P = 0.15) or procedure: gastroscopy, n = 87:39.43 +/- 9.9, flexible sigmoidoscopy/colonoscopy: n = 93:41.86 +/- 9.75 (P = 0.98). No difference was found in anxiety scores in the control group (n = 88) at baseline and immediately pre-endoscopy (P = 0.243), but music led to a significant reduction in anxiety scores (n = 92), which was maintained for all age groups irrespective of procedure (all P < 0.0001). CONCLUSIONS: Anxiety levels in patients attending for endoscopy were not influenced by age or procedure, but were significantly reduced by listening to music compared to controls. The availability of music within the endoscopy unit is a simple strategy that will improve the well-being of patients.

Patients' satisfaction: an important factor in quality control of gastroscopies.

OBJECTIVE: Although oesophagogastroduodenoscopies (OGDs) are associated with few medical complications, substantial pre-procedural anxiety and discomfort during the procedure have been reported. The aims of the present study were to evaluate OGD-related discomfort assessed by the patient and to identify the possibilities for improvement. MATERIAL AND METHODS: All outpatients undergoing OGDs at a single centre during 2004 were eligible for the study. On site, the endoscopy team completed a questionnaire on age of patients, gender and the use of sedation/anaesthesia. After the examination, the patients were given a questionnaire focusing on discomfort during and after the examination. The questionnaire was to be completed at home the following day and returned in a prepaid envelope. RESULTS: During the study period, 1283 examinations were registered, giving 92% coverage of OGDs. The patient response rate was 80%. Patients' mean age was 55 years, and 45% were men. The sedation rate was 7.3%. None or only slight discomfort was experienced by 68% of the patients and severe discomfort by 14%. In patients, the odds ratio (OR) for experiencing moderate or severe discomfort decreased with increasing age (OR 0.96, 95% CI 0.95-0.97, p < 0.001). There were significant differences in patient discomfort depending on the level of experience of the endoscopists. CONCLUSIONS: The majority of patients reported no or only slight discomfort during the examination, but as many as 32% did not. Increased use of sedation in selected patients is recommended. Our quality assurance program included a limited number of variables for registration, with satisfactory compliance by endoscopists and patients.

[Patient satisfaction in gastrointestinal endoscopy: results of a multicenter study]. / Satisfacción del paciente con la endoscopia digestiva: resultados de un estudio multicéntrico.

BACKGROUND AND AIM: The aim of this study was to determine the main quality problems perceived by patients in gastrointestinal endoscopy through a satisfaction survey. PATIENTS AND METHODS: A total of 321 patients from five gastrointestinal endoscopy units were included. Telephone interviews using a previously validated questionnaire on several aspects related to the procedure were carried out. Pareto analyses were performed to pinpoint the most common aspects among the vital few causes at each medical center. Based on the questionnaire, the satisfaction indicators were calculated for each center: the overall satisfaction score (the sum of the responses to the eight questions) and the rate of perceived problems (number of questions with a negative response divided by the number of questions asked). RESULTS: The most frequent aspects among the vital few were waiting time for an appointment and discomfort during the examination, since both factors were included in the vital few in four of the five medical centers. Significant differences were found among centers in the overall satisfaction score (questionnaire score) (p < 0.001) and for the rate of perceived problems (p < 0.001). CONCLUSION: According to the patients, the most problematic aspects were waiting time until the day of the appointment and discomfort during the examination. Perceived quality differed among the participating centers.

An investigation into the information received by patients undergoing a gastroscopy in a large teaching hospital in Ireland.

The purpose of this article is to examine the information received by patients undergoing a gastroscopy. The growing number and complexity of day-case endoscopy increases the need for quality patient information. Provision of patient information reduces anxiety, increases knowledge, improves cooperation during endoscopy and increases compliance with discharge instructions. The study used a descriptive survey with convenience sampling (response rate 66%, N = 137). Patients received most of the standard procedural information (how and why the procedure is carried out), but they received considerably less sensory information (information regarding what they would hear, feel, smell, etc.). In addition, age and gender appeared to affect the amount of information received. Older patients received more procedural information than younger patients, and male patients received more information than female patients. The nurse was the main source of information. The majority of patients (>80%) received adequate information and were satisfied with the information received. Patients also received most of the information verbally on the day of the procedure rather than before admission. This study identified the need for patient information leaflets. The role of the nurse and the effect of age and gender on information provision are important considerations for healthcare professionals.

The frequency of the psychiatric symptoms in the patients with dyspepsia at a university hospital.

OBJECTIVE: According to the psychiatric hypothesis, the symptoms of dyspepsia may be due to depression, anxiety or a somatization disorder. We investigated the frequency of psychiatric symptoms in patients undergoing endoscopic procedures with dyspepsia, either with or without pathological findings, and compared this with control subjects without dyspeptic symptoms. METHODS: Ninety patients with dyspeptic symptoms and 90 control subjects participated in the study. Both the patients and the controls were asked to complete a questionnaire about socio-demographic characteristics, the Turkish version of the Spielberger State-Trait Anxiety Inventory (STAI) and the Symptom Check List-90 (SCL-90). In order for us to determine whether the criteria for any of the conditions listed in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) were met, the patients were asked to take part in the Structured Clinical Interview for DSM-IV disorders. RESULTS: Of the participants, 47.8% had a psychiatric disorder according to DSM-IV criteria, somatoform disorder (44.2%) being the most common. While 42.2% patients were determined to have a pathological finding using endoscopic evaluation, 57.8% had no findings. Together with the somatization and obsessive-compulsive disorder subscale scores, the total SCL-90 score and the mean trait anxiety score were statistically significantly higher in participants with no pathological findings. There were trends for anxiety (13.2% vs. 7.7%) and mood (2.6% vs. 0.0%) disorders to be more frequent in patients with pathological findings, while somatoform disorder+depressive disorder (17.3% vs. 5.2%) was more frequent in patients with no findings, although the differences were not statistically significant (Z=0.7, P>.05). The scores of state-trait anxiety, somatization, obsession-compulsion, depression, anxiety, phobic anxiety and psychotism subscales, and the total SCL-90 score were statistically significantly higher in those participants without a pathological finding than in the controls. CONCLUSIONS: Regarding the high frequency of psychiatric disorders in patients with dyspeptic symptoms, we think that such patients should be evaluated by two separate departments, gastroenterology and psychiatry.

Acceptance of colonoscopy requires more than test tolerance.

BACKGROUND: Colon cancer screening, including colonoscopy, lags behind other forms of cancer screening for participation rates. The intrinsic nature of the endoscopic procedure may be an important barrier that limits patients from finding this test acceptable and affects willingness to undergo screening. With colon cancer screening programs emerging in Canada, test characteristics and their impact on acceptance warrant consideration. OBJECTIVES: To measure the acceptability of colonoscopy and define factors that contribute to procedural acceptability, in relation to another invasive gastrointestinal scope procedure, gastroscopy. PATIENTS AND METHODS: Consecutive patients undergoing a colonoscopy (n=55) or a gastroscopy (n=33) were recruited. Their procedural experience was evaluated and compared pre-endoscopy, immediately before testing and postendoscopy. Questionnaires were used to capture multiple domains of the endoscopy experience and patient characteristics. RESULTS: Patient scope groups did not differ preprocedurally for general or procedure-specific anxiety. However, the colonoscopy group did anticipate more pain. Those who had a gastroscopy demonstrated higher preprocedural acceptance than those who had a colonoscopy. The colonoscopy group had a significant decrease in scope concerns and anxiety postprocedurally. As well, they reported less pain than they anticipated. Regardless, postprocedurally, the colonoscopy group's acceptance did not increase significantly, whereas the gastroscopy group was almost unanimous in their test acceptance. The best predictor of pretest acceptability of colonoscopy was anticipated pain. CONCLUSIONS: The findings indicate that concerns that relate specifically to colonoscopy, including anticipated pain, influence acceptability of the procedure. However, the experience of a colonoscopy does not lead to improved test acceptance, despite decreases in procedural anxiety and pain. Patients' preprocedural views of the test are most important and should be addressed directly to potentially improve participation in colonoscopy.

The role of an information sheet in patient led decision making about sedation and anaesthesia during gastroscopy.

INTRODUCTION: The need for patients to be informed about their disease and its management is now widely recognised, as well as their right to make decisions, which might conflict with the views of their clinicians. There remains a need for the clinician to ensure that patients are provided with accurate evidence-based information. This should be in a form which can be readily understood, retained and acted upon. In order to identify patients' views and to establish evidence of this process there is a need to develop decision trees, which demonstrate their active involvement. AIMS AND METHODS: A short text was designed to outline choices available to patients who were to undergo a gastroscopy. Its purpose was to describe the forms of sedation available and provide information which would allow patients to make an informed choice. The design was such that choices were to be made by patients in an active way and recorded on a document signed by the patient. RESULTS: 97 successive patients completed the choices on an information sheet allowing them to select the nature of their sedation and oral preparation for the procedure. Of these 13 were of South Asian origin and 44 women. 91% of patients wanted some form of sedation or oral anaesthesia. Most (45%) chose lidocaine spray alone, although 5% wished the procedure to be done under a general anaesthetic. 26% of patients wanted the endoscopist to make choices. CONCLUSIONS: In summary, patient choice should include the form of sedation or topical anaesthesia in endoscopic practice. The development of a decision tree is an effective way of providing information and recording a patient's choice.

Factors associated with non-attendance at outpatient endoscopy.

OBJECTIVE: Non-attendance at endoscopy procedures leads to wasted resources and increased costs. The purpose of this study was to investigate the factors associated with non-attendance. MATERIAL AND METHODS: All patients who attended the outpatient clinic for gastroscopy or colonoscopy examinations were included in the study. Patients who missed their appointment were identified and their data were collected prospectively. Patients who kept their appointment in the same period of time served as controls. RESULTS: Between August 2002 and February 2003, 1051 gastroscopies and 756 colonoscopies were scheduled. A total of 265 patients (14.7%) missed their appointment. No significant differences were found between attendees and non-attendees for mean age, gender, type of examination and day of the week on which the examination was scheduled. The time on the waiting list was longer in patients who did not keep their appointment than in those who did. Fewer appointments were missed in patients with a preferent referral, and among patients referred by their general practitioner a higher percentage failed to keep their appointment compared with those referred by a specialist. In the multivariate analysis, length of time on the waiting list and the source of referral were the only two independent predictive factors for non-attendance. CONCLUSIONS: A longer time on the waiting list and referral by a general practitioner are factors associated with patients failing to keep their endoscopy appointment.
