Rethink analgo-sedation in digestive endoscopy: the role of scientific societies in tracing training path.

OBJECTIVE: The Italian Society of Anesthesia, Analgesia, Reanimation and Intensive Care Medicine (SIAARTI) and the Italian Society of Digestive Endoscopy (SIED) worked together to produce a joint Good Clinical Practice (GCP) on analgo-sedation in digestive endoscopy and launched a survey to support the document. The aim was to identify and describe the actual clinical practice of sedation in Italian digestive endoscopy units and offer material for a wider and more widespread discussion among anesthetists and endoscopists. SUBJECTS AND METHODS: A national survey was planned, in order to support the statements of the GCP. Twelve thousand and five hundred questionnaires were sent to the members of SIAARTI and SIED in June 2020. RESULTS: A total of 662 forms (5.3%) returned completed. Highly complex procedures are performed according to 70% of respondents; daily anesthesiologist's assistance is guaranteed in 26%, for scheduled sessions in 14.5% and as needed in 8%. 69% of respondents declared not to have a dedicated team of anesthesiologists, while just 5% reported an anesthesiologist in charge. A complete monitoring system was assured by 70% of respondents. Dedicated pathways for COVID-19-positive patients were confirmed in <40% of the answers. With regard to moderate/deep sedation, 90% of respondents stated that an anesthetist decides timing and doses. Propofol was exclusively administered by anesthetists according to 94% of answers, and for 6% of respondents the endoscopist is allowed to administer propofol in presence of a dedicated nurse, but with a readily available anesthetist. Only 32.8% of respondents reported institutional training courses on procedural analgo-sedation. CONCLUSIONS: The need to provide patients scheduled for endoscopy procedures with an adequate analgo-sedation is becoming an increasing concern, well-known in almost all countries, but many factors compromise the quality of patient care. Results of a national survey would give strength to the need for a shared GCP in gastrointestinal endoscopy. Training and certification of non-anesthetist professionals should be one of the main ways to center the objective.

The management of endoscopic retrograde cholangio- pancreatography-related infections risk: results of an italian survey at regional level.

Background and aim: Among the Endoscopic retrograde cholangiopancreatography (ERCP) adverse events, an increasingly arising problem is the transmission of Multi Drug Resistant (MDR) Bacteria through duodenoscopes. The aim of this survey was to evaluate the current clinical practice of management of ERCP associated infections in Emilia-Romagna, Italy. Methods: An online survey was developed including 12 questions on management of ERCP associated infections risk. The survey was proposed to all 12 endoscopy centers in Emilia Romagna that perform at least > 200 ERCPs per year. Results: 11 centers completed the survey (92%). Among all risk factors of ERCP infections, hospitalization in intensive care units, immunosuppressant therapies, and previous MDR infections have achieved a 80 % minimum of concurrence by our respondents. The majority of them did not have a formalized document in their hospital describing categories and risk factors helpful in the detection of patients undergoing ERCP with an high-level infective risk (9/11, 82%). Most centers (8/11, 72%) do not perform screening in patients at risk of ERCP infections. Post procedural monitoring is performed by 6 of 11 centers (55%). Conclusion: Our survey showed that, at least at regional level, there is a lack of procedures and protocols related to the management of patients at risk of ERCP infections.

Optimal processing of ESD specimens to avoid pathological artifacts.

BACKGROUND: En bloc endoscopic submucosal dissection (ESD) has been recently introduced as a treatment for precancerous/neoplastic gastrointestinal conditions. The aim of the present study was histological assessment of en bloc ESD specimens. METHODS: Fifty-three ESD specimens were positioned over a cellulose acetate support (40 specimens; 12 from the upper gastrointestinal tract and 28 from the lower gastrointestinal tract) or pinned with nails on polystyrene or cork (13 specimens; 7 from the upper gastrointestinal tract and 6 from the lower gastrointestinal tract). We cut consecutive 2 mm-thick sections stained with hematoxylin and eosin. From the first and the last sections, we obtained a second slide, after a 180° rotation and re-embedding. The quality of ESD samples was scored as inadequate, suboptimal and adequate, based on the amount of crushing, shearing and stretching artifacts that were scored from 0 (absent) to 2 (diffuse or maximum). From the sum of these we obtained a global artifact score (GAS). RESULTS: Removed lesions were: adenocarcinoma (5 cases), neuroendocrine tumor (NET) G1 (1 case), premalignant conditions, including adenomatous polyps (41 cases) and hyperplastic lesions (6 cases). A positive deep surgical margin was found in 8/53 cases (15%): high- and low-grade dysplastic glands were detected in 5 cases, low-grade adenocarcinoma in 2, and NET cells in 1. Dysplastic glands were detected in the lateral surgical margins of 12 ESD specimens (23%). Among the ESD specimens positioned on the cellulose acetate support, apart from the modifications due to electrocoagulation, 2 (5%) showed shearing modifications. In the group of ESD specimens fixed with nails, 5 (38%) showed shearing, 10 (77%) crushing artifacts, 11 (85%) stretching and 11 (85%) multiple holes caused by the nails. On the basis of these data all histological specimens from ESD on cellulose acetate were adequate (GAS 0-1).However, in the group of ESD fixed with nails, 1 was adequate (GAS 0), 11 suboptimal (GAS 2-5) and 1 inadequate (GAS 6). CONCLUSIONS: Specific devices including cellulose support and adequate sampling blocks can be helpful to perform accurate histological assessment of ESD specimens after en bloc ESD for precancerous/neoplastic gastrointestinal lesions, with complete analysis of the status of the margins and the entirely en bloc evaluation of the lesion.

Postreflux swallow-induced peristaltic wave index and nocturnal baseline impedance can link PPI-responsive heartburn to reflux better than acid exposure time.

BACKGROUND: Acid exposure time (AET) is considered the most useful parameter to predict response of reflux-related heartburn to medical or surgical treatment. However, recent studies showed high rates of heartburn response to proton pump inhibitor (PPI) therapy in patients with normal AET. We aimed to compare the efficacy of postreflux swallow-induced peristaltic wave (PSPW) index and mean nocturnal baseline impedance (MNBI) with AET in linking PPI-responsive heartburn to reflux. METHODS: Off-therapy impedance-pH tracings from 425 patients, 317 with PPI-responsive and 108 with PPI-refractory heartburn were blindly re-analyzed. Demographic and endoscopic characteristics, conventional impedance-pH variables, PSPW index, and MNBI were assessed with multivariate logistic regression to identify factors independently associated with PPI responsiveness. Prediction models were developed to assess the strength of reflux linkage with factors independently associated with PPI responsiveness by calculating the area under the curve (AUC) at receiver-operating-characteristic (ROC) analysis. KEY RESULTS: At multivariate logistic regression analysis, AET, MNBI, and PSPW index were the only factors independently associated with PPI responsiveness, abnormal values found in 60%, 76%, and 92% of PPI-responsive cases (P<.017). At ROC analysis, PSPW index (AUC:.794, P=.002) and MNBI (AUC: 0.742, P=.003), both separately and combined (AUC: 0.811, P<.001) linked reflux with PPI-responsiveness better than AET (AUC: 0.687). CONCLUSIONS & INFERENCES: AET, PSPW index, and MNBI are independently associated with PPI-responsive heartburn. PSPW index and MNBI can link PPI-responsive heartburn to reflux better than AET and should become part of the standard analysis of impedance-pH tracings.

Neoplastic progression in short-segment Barrett's oesophagus is associated with impairment of chemical clearance, but not inadequate acid suppression by proton pump inhibitor therapy.

BACKGROUND: Pathophysiological mechanisms associated with neoplastic progression in patients with short-segment Barrett's oesophagus (SSBO), who represent the vast majority of the Barrett population, have not been defined. AIM: To evaluate pathophysiological characteristics of patients with SSBO and dysplasia detected at 3-year surveillance endoscopy (incident dysplasia). METHODS: Patients with SSBO underwent impedance-pH monitoring during heartburn-suppressing PPI therapy. Fifteen patients (12 males, median age 62 years) with incident dysplasia and 50 patients (43 males, median age 59 years) without dysplasia were compared. Impedance-pH parameters, including chemical clearance assessed by the post-reflux swallow-induced peristaltic wave (PSPW) index, were evaluated. RESULTS: All patients declared persisting heartburn suppression on maintenance PPI therapy at 3-year follow-up, 58/65 (89%) with standard dosages. The median gastric and oesophageal acid exposure time (GAET and OAET) did not differ between patients with and without incident dysplasia at the time of surveillance (36% and 0.6% vs. 33% and 0.5%) or index endoscopy (33% and 0.3% vs. 41% and 0.5%) (P > 0.05). Contrastingly, the median PSPW index was significantly lower in patients with than in patients without incident dysplasia at the time of surveillance (15%, vs. 32%) and index endoscopy (12% vs. 30%) (P = 0.001). The PSPW index, the GAET and the OAET did not vary over time (P > 0.05). A PSPW index <26% was predictive of incident dysplasia with a 75% accuracy. CONCLUSIONS: Neoplastic progression in SSBO is associated with impairment of chemical clearance, but not inadequate acid suppression by PPI therapy. Neoplastic progression in SSBO can be predicted by a low PSPW index.

Radiofrequency ablation for chronic radiation proctitis: our initial experience with four cases.

BACKGROUND: Chronic radiation proctitis (CRP) occurs up to 20 % of patients after pelvic radiotherapy, with rectal bleeding as the main presenting complaint. Radiofrequency ablation (RFA) has recently been used in the management of Barrett's esophagus, but its efficacy in CRP has to be studied. The aim of this case series was to describe four cases of patients with CRP treated with RFA that demonstrate the efficacy and safety of the technique. METHODS: All the procedures were performed with HALO 90 or HALO 90 Ultra ablation catheter fitted on the distal end of a standard flexible endoscope. For each patient, the severity of symptoms was assessed at baseline and after the last treatment session. RESULTS: At least two sessions of RFA (maximum 4) were necessary, at three-month intervals, to completely control the symptoms. No major complications were observed. CONCLUSIONS: RFA was effective and safe for control bleeding in this case series. Adequately powered randomized controlled trials are needed to establish the safety and efficacy of RFA for CRP.

Esophageal chemical clearance is impaired in gastro-esophageal reflux disease--a 24-h impedance-pH monitoring assessment.

BACKGROUND: Impedance-pH monitoring allows assessment of retrograde and antegrade intra-esophageal movement of fluids and gas. Reflux is followed by volume clearance and chemical clearance, elicited by secondary and swallow-induced peristalsis, respectively. We aimed to assess whether chemical clearance is impaired in gastro-esophageal reflux disease (GERD). METHODS: Blinded retrospective review of impedance-pH tracings from patients with erosive reflux disease (ERD) and non-erosive reflux disease (NERD), and from proton pump inhibitor (PPI)-refractory patients before and after laparoscopic fundoplication. The number of refluxes followed within 30 s by swallow-induced peristaltic waves was divided by the number of total refluxes to obtain a parameter representing chemical clearance namely the postreflux swallow-induced peristaltic wave (PSPW) index. KEY RESULTS: The PSPW index was significantly lower in 31 ERD (15%) and in 44 NERD (33%) off-PPI patients than in 30 controls (75%), as well as in 18 ERD (16%) and in 48 NERD (31%) on-PPI patients than in 26 on-PPI functional heartburn (FH) cases (67%) (P < 0.05 for all comparisons). In 29 PPI-refractory patients, the median PSPW index was unaltered by otherwise effective antireflux surgery (20% postoperatively, 21% preoperatively). The overall sensitivity, specificity, positive, and negative predictive values of the PSPW index in identifying GERD patients were 97%, 89%, 96%, and 93%. CONCLUSIONS & INFERENCES: Impairment of chemical clearance is a primary pathophysiological mechanism specific to GERD: it is unaffected by medical/surgical therapy, is not found in FH, and is more pronounced in ERD than in NERD. Using the PSPW index could improve the diagnostic efficacy of impedance-pH monitoring.

The added value of quantitative analysis of on-therapy impedance-pH parameters in distinguishing refractory non-erosive reflux disease from functional heartburn.

BACKGROUND: By analysis of symptom-reflux association, endoscopy-negative refractory heartburn can be related to acid/non-acid refluxes with impedance-pH monitoring. Unfortunately, patients frequently do not report symptoms during the test. We aimed to assess the contribution of quantitative analysis of impedance-pH parameters added to symptom-reflux association in evaluating patients with endoscopy-negative heartburn refractory to high-dose proton pump inhibitor therapy. METHODS: The symptom association probability (SAP), the symptom index (SI), the esophageal acid exposure time and the number of distal and proximal refluxes were assessed at on-therapy impedance-pH monitoring. Relationships with hiatal hernia and manometric findings were also evaluated. KEY RESULTS: Eighty patients were prospectively studied. Refractory heartburn was more frequently related to reflux by a positive SAP/SI and/or abnormal impedance-pH parameters (52/80 cases) (65%) than by a positive SAP/SI only (38/80 cases) (47%) (P = 0.038). In patients with refractory non-erosive reflux disease (NERD) defined by a positive SAP/SI and/or abnormal impedance-pH parameters, the prevalence of hiatal hernia was significantly higher (56%vs 21%, P = 0.007) and the mean lower esophageal sphincter tone was significantly lower (18.7 vs 25.8 mmHg, P = 0.005) than in those (35%) with reflux-unrelated, i.e., functional heartburn (FH). On the contrary, no significant difference was observed subdividing patients according to a positive SAP/SI only. CONCLUSIONS & INFERENCES: Quantitative analysis of impedance-pH parameters added to symptom-reflux association allows a subdivision of refractory-heartburn patients into refractory NERD and FH which is substantiated by pathophysiological findings and which restricts the diagnosis of FH to one third of cases.

Reflux parameters as modified by EsophyX or laparoscopic fundoplication in refractory GERD.

BACKGROUND: EsophyX is a novel transoral incisionless fundoplication device developed to mimic surgical fundoplication. EsophyX fundoplication improves acid reflux parameters in proton pump inhibitor (PPI)-responsive GERD patients but its efficacy in refractory GERD has been scarcely studied. AIM: To assess reflux parameters before and after EsophyX or laparoscopic fundoplication and their relationship with symptoms in refractory GERD. METHODS: In an open-label study, we enrolled prospectively patients with heartburn/regurgitation persisting despite high-dose PPI therapy. Impedance-pH monitoring was performed on PPI therapy before intervention and off PPI therapy 3 months after intervention. RESULTS: Ten patients chose to undergo EsophyX (EndoGastric Solutions, Redmond, WA, USA) fundoplication while ten chose laparoscopic fundoplication, and the baseline characteristics were comparable. Distal and proximal refluxes were significantly reduced post-operatively in the surgical but not in the endoscopic group and the median values were significantly lower in the former than in the latter. The oesophageal acid exposure time was normal in 50% of cases after EsophyX and in 100% of cases after surgery (P=0.033); the number of distal refluxes was normal in 20% and 90% of cases (P=0.005) and the number of proximal refluxes was normal in 40% and 100% of cases (P=0.011), respectively. A positive persisting symptom-reflux association was found post-operatively in 6/10 patients in the EsophyX group and in 0/10 patients in the surgical group (P=0.011). CONCLUSIONS: In patients with refractory GERD, EsophyX fundoplication is significantly less effective than laparoscopic fundoplication in improving reflux parameters and accordingly, in inducing symptom remission.

Use of palmitoylethanolamide in the entrapment neuropathy of the median in the wrist.

AIM: Carpal tunnel syndrome (CTS) is a medical condition in which the median nerve is compressed, leading to discomfort and pain. Palmitoylethanolamide (PEA) is an endogenous fatty acid amide, able to modulate inflammatory cell reactivity and pain. This study deals with the capability of PEA to normalize the electroneurographic alterations associated with moderate CTS. METHODS: Patients displaying moderate CTS were enrolled and daily PEA (600 mg or 1 200 mg/die) was administered for 30 days. Control group received no treatment. RESULTS: PEA treatment significantly improved the CTS-induced reduction of median nerve latency time (P<0.0004); PEA effect was dose-dependent. Tinel's sign presence and symptoms of discomfort were also reduced. CONCLUSION: Although further studies are needed to better characterize PEA effect, the present report represents the first evidence on the improvement of distal motor latency elicited by PEA in patients with moderate CTS. The data support the hypothesis of protection against inflammatory and neuropathic pain by PEA.

Endoscopic treatment of gastrointestinal fistulas using an over-the-scope clip (OTSC) device: case series from a tertiary referral center.

Gastrointestinal perforations and post-surgical fistulas are dreaded complications that dramatically increase morbidity and mortality. A new endoscopic over-the-scope clip (OTSC) system may be potentially useful for sealing visceral perforations in several clinical settings. We evaluated the advantages and clinical impact of the placement of OTSCs on the management of non-malignant gut leaks in 12 consecutive patients. OTSCs of 9.5 or 10.5 mm were used, according to the diameter of the defect within the wall. The indications for treatment were mainly related to post-surgical fistulas. Healing of the fistula was assessed by endoscopic or radiological means, and failed only once. No OTSC-related complications occurred. Endoscopic closure of perforations and post-surgical fistulas with the OTSC system is a simple and minimally invasive technique. This approach, when feasible, may be less expensive and more advantageous than a surgical approach.

Weakly acidic refluxes have a major role in the pathogenesis of proton pump inhibitor-resistant reflux oesophagitis.

BACKGROUND: In patients with heartburn that persists despite proton pump inhibitor (PPI) therapy, reflux oesophagitis is found rarely, and its pathogenesis has been scarcely studied. AIM: To assess reflux parameters by impedance-pH monitoring in PPI-resistant reflux oesophagitis. METHODS: Impedance-pH monitoring was performed on PPI therapy in patients with symptomatic reflux oesophagitis detected despite standard or high-dose PPI therapy of at least 8-week duration. RESULTS: Twenty patients, ten on once daily and ten on twice daily PPI regimens, were studied. The gastric acid exposure time (per cent time pH <4) ranged from 10% to 81% and was >30% in 70% of cases, but the oesophageal acid exposure time (per cent time pH <4) was abnormal in 20% of patients only. The number of acid, weakly acidic and weakly alkaline refluxes was abnormal in 25%, 100% and 15% of patients, respectively. CONCLUSIONS: Weakly acidic refluxes were above the normal range in all cases, whereas acid reflux parameters and weakly alkaline refluxes were normal in the vast majority of cases. Gastric acid secretion, with consequent intra-gastric pepsins activation, persists despite ongoing PPI therapy and activated pepsins may well be present in weakly acidic refluxes. As activated pepsins maintain their proteolytic activity in a weakly acidic environment, they may be responsible for mucosal damage. We conclude that weakly acidic refluxes have a major role in the pathogenesis of PPI-resistant reflux oesophagitis. Therapeutic interventions in patients with PPI-resistant reflux oesophagitis should be tailored on the basis of impedance-pH-monitoring results.

Reflux patterns in patients with short-segment Barrett's oesophagus: a study using impedance-pH monitoring off and on proton pump inhibitor therapy.

BACKGROUND: In short-segment Barrett's oesophagus (SSBO) heartburn may be absent and oesophageal acid exposure time (OAET) assessed with pH-only monitoring may be normal. By detecting reflux episodes independently of their acidity, multichannel intraluminal impedance-pH (MII-pH) monitoring allows a comprehensive characterization of reflux events, either off or on proton pump inhibitor (PPI) therapy. AIM: To assess reflux parameters by MII-pH monitoring in newly diagnosed SSBO, at baseline and as modified with PPI therapy. METHODS: Short-segment Barrett's oesophagus was defined by oesophageal intestinal metaplasia up to 3 cm in length. 24-h MII-pH monitoring was performed before and during PPI therapy. RESULTS: Fifty patients were studied prospectively. Normal OAET was found at baseline in 15 patients (30%), 8 and 2 of whom with a higher than normal number of acid and weakly acidic refluxes, respectively. Overall, abnormal reflux parameters were detected by MII-pH monitoring in 90% of patients. Reflux events were prevalent in the upright period. On PPI therapy, acid refluxes decreased and a correspondent increase in weakly acidic refluxes was observed (median from 48.5 to 9 and from 16 to 57.5, respectively) (P < 0.001). CONCLUSIONS: Acid refluxes, mainly in the upright period, characterize SSBO. PPI therapy transforms acid refluxes into weakly acidic refluxes.

Turning off artistic ability: the influence of left DBS in art production.

BACKGROUND: The influence of Parkinson's disease (PD) as well as deep brain stimulation (DBS) on visual-artistic production of people who have been artists is unclear. We systematically assessed the artistic-creative productions of a patient with PD who was referred to us for management of a left subthalamic region (STN) DBS. The patient was an artist before her disease started, permitting us to analyze changes in her artistic-creative production over the course of the illness and during her treatment with DBS. METHODS: We collected her paintings from four time periods: Time 1 (Early Pre-Presymptomatic), Time 2 (Later Presymptomatic), Time 3 (Symptomatic), and Time 4 (DBS Symptomatic). A total of 59 paintings were submitted to a panel of judges, who rated the paintings on 6 different artistic qualities including: aesthetics, closure, evocative impact, novelty, representation, technique. RESULTS: Aesthetics and evocative impact significantly declined from Time 2 to Time 4. Representation and technique indicated a curvilinear relationship, with initial improvement from Time 1 to Time 2 followed by a decline from Time 2 to Time 4. CONCLUSIONS: These results suggest that left STN/SNR-DBS impacted artistic performances in our patient. The reason for these alterations is not known, but it might be that alterations of left hemisphere functions induce a hemispheric bias reducing the influence the right hemisphere which is important for artistic creativity. The left hemisphere itself plays a critical role in artistic creativity and DBS might have altered left hemisphere functions or altered the mesolimbic system which might have also influenced creativity. Future studies will be required to learn how PD and DBS influence creativity.

Implementation of sedation guidelines in clinical practice in Italy: results of a prospective longitudinal multicenter study.

BACKGROUND AND STUDY AIMS: Following publication in 2000 of the Italian Guidelines for Sedation in Digestive Endoscopy, the authors carried out a dissemination program and an audit of the impact of the Guidelines in clinical practice. The primary aim was to evaluate any changes in sedation methods at the start of and during the study period (at 0, 6, and 12 months). Secondary study aims were detailed analyses of endoscopies regarding sedation, complications, and patient satisfaction. PATIENTS AND METHODS: The prospective, observational, multicenter study was commenced in 60 centers (31 first- and 29 second-level) which opted to have seminars on the Guidelines; results concerning sedation practices in relation to endoscopic procedure, complications, and patient satisfaction were recorded at the start of the study (phase 0) and at 6 and 12 months. Over a 1-year period, 5261 sedated and unsedated patients undergoing endoscopic procedures were enrolled (with data collection between December 1999 and June 2002). The results were analyzed using the chi-squared test. RESULTS: Data were available for all three assessment time points from 29 of the 60 centers. The sedation rate, between phase 0 and 2, increased by 12.75% in first-level centers and 0.73% in second-level centers with midazolam use increasing from 34% to 41%. For colonoscopy, sedation usage increased from 52% to 56%. Adverse events occurred in 0.47% of the patients, without long-term sequelae or death, and patient satisfaction was only slightly, but not significantly higher with sedation (90.4% of sedated patients were "very satisfied" vs. 87% of unsedated patients who were "satisfied"), but the examination was more likely to be complete in sedated patients and this difference was statistically significant ( P < 0.001). CONCLUSIONS: We conclude that if sedation is used as recommended by the Guidelines, it is possible to control clinical risk by using high quality endoscopic procedures.

Giant abdominal stromal cell tumour diagnosed at endoscopic ultrasonography: is there a need for systematic use of endoscopic ultrasonography in submucosal gastric tumours?

A giant abdominal stromal cell tumour was diagnosed at endosonography performed for a relatively small gastric submucosal lesion. Although the case is rare, it draws attention to the need for systematic investigations with endoscopic ultrasonography in any submucosal lesion.

Effects of two types of brief intervention and readiness to change on alcohol use in hazardous drinkers.

OBJECTIVE: Brief interventions for hazardous and low-dependent drinkers in the primary care setting have considerable empirical support. The purpose of this study was to (1) evaluate the effects of brief advice (BA) and motivational enhancement (ME) interventions on alcohol consumption. In addition, a hindsight matching design was used to (2) study the moderator effects of patient readiness to change (alcohol use) on alcohol consumption. METHOD: The subjects (N = 301, 70% men) were patients 21 years of age or older who presented for treatment at one of 12 primary care clinics. After screening for eligibility and providing consent to participate in the study, the patients completed a baseline assessment and were randomly assigned to the BA, ME or standard care (SC) interventions condition. Follow-up assessments were completed at 1-, 3-, 6-, 9- and 12-months postbaseline assessment. RESULTS: Evaluation of the first hypothesis (n = 232 for these analyses) showed that all participants tended to reduce their alcohol use considerably between the baseline and 12-month assessments. In addition, evaluation of the second hypothesis showed a moderator effect of readiness to change in predicting the number of drinks at 12 months, such that the BA intervention seemed more effective for patients relatively low in readiness to change compared to those higher in readiness. Readiness to change did not seem to be related to changes in drinking of participants in the SC or ME conditions. CONCLUSIONS: The results confirm that, among primary care patients, substantial changes in alcohol consumption are possible. They further suggest that matching studies of patient readiness to change their alcohol use, as well as other variables, are warranted.
