The Support, Educate, Empower personalized glaucoma coaching trial design.

BACKGROUND: Glaucoma is a chronic disease that affects 3 million Americans. Glaucoma is most often asymptomatic until very late in its course when treatment is more difficult and extensive peripheral vision loss has already occurred. Taking daily medications can mitigate this vision loss, but at least half of people with glaucoma do not take their prescribed medications regularly. The purpose of this study is to improve glaucoma medication adherence among those with medically treated glaucoma and poor self-reported adherence using the Support, Educate, Empower personalized coaching program. METHODS/DESIGN: This study is a two-site randomized controlled trial enrolling 230 participants with poor self-reported glaucoma medication adherence. The trial has two arms, an intervention arm and a control arm. Participants in the intervention arm receive personalized glaucoma education and motivational interviewing-based coaching over 6 months from a trained non-physician interventionist for three in-person sessions with between visit phone calls for check-ins where current adherence level is reported to participants. Participants also can elect to have visual, audio, text or automated phone call medication dose reminders. Participants in the control arm continue usual care with their physician and receive non-personalized glaucoma educational materials via mail in parallel to the three in-person coaching sessions to control for glaucoma knowledge content. All participants receive a medication adherence monitor. The primary outcome is the proportion of prescribed doses taken on schedule during the 6-month period. The secondary outcome is glaucoma related distress. The exploratory outcome is intraocular pressure. DISCUSSION: The personalized education and motivational-interviewing-based intervention that we are testing is comprehensive in that it addresses the wide range of barriers to adherence that people with glaucoma encounter. Leveraging a custom-built web-based application to generate the personalized content and the motivational-interviewing-based prompts to guide the coaching sessions will make this program both replicable and scalable and can be integrated into clinical care utilizing trained non-physician providers. Although this type of self-management support is not currently reimbursed for glaucoma as it is for diabetes, this trial could help shape future policy change should the intervention be found effective.

Michigan Screening and Intervention for Glaucoma and Eye Health Through Telemedicine (MI-SIGHT): Baseline Methodology for Implementing and Assessing a Community-based Program.

PRECIS: The Michigan Screening and Intervention for Glaucoma and eye Health through Telemedicine (MI-SIGHT) program leverages community-engaged research, telemedicine, and health coaching to overcome key logistical and psychosocial barriers to improve glaucoma screening in underserved communities. PURPOSE: To describe the methodology of the implementation and evaluation of the MI-SIGHT Program. METHODS: The MI-SIGHT Program uses community engagement, telemedicine, and health coaching to overcome key logistical and psychosocial barriers to glaucoma identification and care among underserved populations. The MI-SIGHT Program will be evaluated in 2 community clinics: Hamilton Community Health Network, a federally qualified health center in Flint, Michigan, and the Hope Clinic, a free clinic in Ypsilanti, Michigan. A Community Advisory Board including the research team and health care providers, administrators, and patients from both clinics will guide program implementation. An ophthalmic technician at the community clinics will conduct screening tests for glaucoma and eye disease. The data will be transmitted through electronic health record to be reviewed by an ophthalmologist who will make recommendations for follow-up care. The ophthalmic technician will conduct a return visit to fit low-or no-cost glasses, help arrange follow-up with an ophthalmologist, and provide education. Those diagnosed with glaucoma or suspected glaucoma will be randomized to standard education or personalized glaucoma education and coaching. Costs will be assessed. RESULTS: The authors hypothesize that the MI-SIGHT Program will detect a higher prevalence rate of glaucoma than that found in the general population, improve upon presenting visual acuity, enhance vision-related quality of life, and demonstrate that personalized glaucoma education and coaching improve adherence to follow-up care. CONCLUSION: The MI-SIGHT Program may serve as a model for glaucoma screening and care in high-risk communities.

The variability in how physicians think: a casebased diagnostic simulation exercise.

OBJECTIVES: Little is known about how physician diagnostic thinking unfolds over time when evaluating patients. We designed a case-based simulation to understand how physicians reason, create differential diagnoses, and employ strategies to achieve a correct diagnosis. METHODS: Between June 2017 and August 2018, hospital medicine physicians at two academic medical centers were presented a standardized case of a patient presenting with chest pain who was ultimately diagnosed with herpes zoster using an interview format. Case information was presented in predetermined aliquots where participants were then asked to think-aloud, describing their thoughts and differential diagnoses given the data available. At the conclusion of the interview, participants were asked questions about their diagnostic process. Interviews were recorded, transcribed, and content analysis was conducted to identify key themes related to the diagnostic thinking process. RESULTS: Sixteen hospital medicine physicians (nine men, seven women) participated in interviews and four obtained the correct final diagnosis (one man, three women). Participants had an average of nine years of experience. Overall, substantial heterogeneity in both the differential diagnoses and clinical reasoning among participants was observed. Those achieving the correct diagnosis utilized systems-based or anatomic approaches when forming their initial differential diagnoses, rather than focusing on life-threatening diagnoses alone. Evidence of cognitive bias was common; those with the correct diagnosis more often applied debiasing strategies than those with the incorrect final diagnosis. CONCLUSIONS: Heterogeneity in diagnostic evaluation appears to be common and may indicate faulty data processing. Structured approaches and debiasing strategies appear helpful in promoting diagnostic accuracy.

Visual arts in the clinical clerkship: a pilot cluster-randomized, controlled trial.

BACKGROUND: Arts exposure is associated with positive psychological constructs. To date, no randomized, controlled studies have integrated art into clinical medical education or measured its effects on positive psychological constructs or educational outcomes. In this study, we assessed the possibility and potential benefits of integrating visual arts education into a required internal medicine (IM) clinical clerkship. METHODS: We conducted a controlled trial in an academic healthcare system with an affiliated art museum. IM students were assigned to one of three interventions: museum-based arts (n = 11), hospital-based arts (n = 10), or hospital-based conventional education (n = 13). Arts groups explored empathy, resilience, and compassion in works of art during facilitator-guided discussions. We assessed pre- and post-intervention measures of empathy, mindfulness, tolerance of ambiguity, and grit and tracked National Board of Medical Examiners IM shelf exam performance to capture changes in educational outcomes. Focus group discussions with participants in the arts-based interventions were performed at the study's conclusion. RESULTS: Arts education was successfully integrated into a busy clinical clerkship in both hospital and art museum settings. Focus group participants reported increased implicit bias cognizance and time for reflection, but no significant differences in psychometric or educational outcomes were identified. While most students felt positively toward the experience; some experienced distress from missed clinical time. CONCLUSIONS: This pilot study demonstrates the feasibility of integrating visual arts education into the clerkship. Although observable quantitative differences in measures of positive psychological constructs and educational outcomes were not found, qualitative assessment suggested benefits as well as the feasibility of bringing fine arts instruction into the clinical space. A larger, multi-center study is warranted.

A physician-pharmacist collaborative care model to prevent opioid misuse.

PURPOSE: Clinical pharmacists in primary care clinics can potentially help manage chronic pain and opioid prescriptions by providing services similar to those provided within their scope of practice to patients with diabetes and hypertension. We evaluated the feasibility and acceptability of a pharmacist-physician collaborative care model for patients with chronic pain. METHODS: The program consisted of an in-person pharmacist consultation and optional follow-up visits over 4 months in 2 primary care practices. Eligible patients had chronic pain and a long-term prescription for opioids or buprenorphine or were referred by their primary care physician (PCP). Pharmacist recommendations were communicated to PCPs via the electronic medical record (EMR) and direct communication. Mixed-methods evaluation included baseline and follow-up surveys with patients, EMR review of opioid-related clinical encounters, and provider interviews. RESULTS: Between January and October 2018, 47 of the 182 eligible patients enrolled, with 46 completing all follow-up; 43 patients (91%) had received opioids over the past 6 months. The pharmacist recommended adding or switching to a nonopioid pain medication for 30 patients, switching to buprenorphine for pain and complex persistent opioid dependence for 20 patients, and tapering opioids for 3 patients. All physicians found the intervention acceptable but wanted more guidance on prescribing buprenorphine for pain. Most patients found the intervention helpful, but some reported a lack of physician follow-up on recommended changes. CONCLUSION: The study demonstrated that comanagement of patients with chronic pain is feasible and acceptable. Policy changes to increase pharmacists' authority to prescribe may increase physician willingness and confidence to carry out opioid tapers and prescribe buprenorphine for pain.

Do bedside whiteboards enhance communication in hospitals? An exploratory multimethod study of patient and nurse perspectives.

OBJECTIVE: To understand patient and nurse views on usability, design, content, barriers and facilitators of hospital whiteboard utilisation in patient rooms. DESIGN: Multimethods study. SETTING: Adult medical-surgical units at a quaternary care academic centre. PARTICIPANTS: Four hundred and thirty-eight adult patients admitted to inpatient units participated in bedside surveys. Two focus groups with a total of 13 nurses responsible for updating and maintaining the whiteboards were conducted. RESULTS: Most survey respondents were male (55%), ≥51 years of age (69%) and admitted to the hospital ≤4 times in the past 12 months (90%). Over 95% of patients found the whiteboard helpful and 92% read the information on the whiteboard frequently. Patients stated that nurses, not doctors, were the most frequent user of whiteboards (93% vs 9.4%, p<0.001, respectively). Patients indicated that the name of the team members (95%), current date (87%), upcoming tests/procedures (80%) and goals of care (63%) were most useful. While 60% of patients were aware that they could use the whiteboard for questions/comments for providers, those with ≥5 admissions in the past 12 months were significantly more likely to be aware of this aspect (p<0.001). In focus groups, nurses reported they maintained the content on the boards and cited lack of access to clinical information and limited use by doctors as barriers. Nurses suggested creating a curriculum to orient patients to whiteboards on admission, and educational programmes for physicians to increase whiteboard utilisation. CONCLUSION: Bedside whiteboards are highly prevalent in hospitals. Orienting patients and their families to their purpose, encouraging daily use of the medium and nurse-physician engagement around this tool may help facilitate communication and information sharing.

Review article: Let us talk about snakebite management: A discussion on many levels.

We want to discuss antivenom use in snakebite clinical practice guidelines. Coronial reviews in Victoria of two cases of snakebite envenomation, one described in detail below, prompted us to submit this paper for a wider audience and debate. Venom and antivenom levels were measured in the case detailed below, but not in the other. The coroner received conflicting and varied advice from experts regarding the dose of antivenom. The Victorian Department of Health and Human Services and the Australasian College for Emergency Medicine were instructed to review snakebite management guidelines, particularly with respect to antivenom dosage. The discussion that took place among medical experts led to considerable media attention. We discuss the potential fallout when there is no consensus among medical experts.

Electronic health records, communication, and data sharing: challenges and opportunities for improving the diagnostic process.

Background Diagnosis requires that clinicians communicate and share patient information in an efficient manner. Advances in electronic health records (EHRs) and health information technologies have created both challenges and opportunities for such communication. Methods We conducted a multi-method, focused ethnographic study of physicians on general medicine inpatient units in two teaching hospitals. Physician teams were observed during and after morning rounds to understand workflow, data sharing and communication during diagnosis. To validate findings, interviews and focus groups were conducted with physicians. Field notes and interview/focus group transcripts were reviewed and themes identified using content analysis. Results Existing communication technologies and EHR-based data sharing processes were perceived as barriers to diagnosis. In particular, reliance on paging systems and lack of face-to-face communication among clinicians created obstacles to sustained thinking and discussion of diagnostic decision-making. Further, the EHR created data overload and data fragmentation, making integration for diagnosis difficult. To improve diagnosis, physicians recommended replacing pagers with two-way communication devices, restructuring the EHR to facilitate access to key information and improving training on EHR systems. Conclusions As advances in health information technology evolve, challenges in the way clinicians share information during the diagnostic process will rise. To improve diagnosis, changes to both the technology and the way in which we use it may be necessary.

Characteristics of healthcare organisations struggling to improve quality: results from a systematic review of qualitative studies.

BACKGROUND: Identifying characteristics associated with struggling healthcare organisations may help inform improvement. Thus, we systematically reviewed the literature to: (1) Identify organisational factors associated with struggling healthcare organisations and (2) Summarise these factors into actionable domains. METHODS: Systematic review of qualitative studies that evaluated organisational characteristics of healthcare organisations that were struggling as defined by below-average patient outcomes (eg, mortality) or quality of care metrics (eg, Patient Safety Indicators). Searches were conducted in MEDLINE (via Ovid), EMBASE, Cochrane Library, CINAHL, and Web of Science from database inception through February 8 2018. Qualitative data were analysed using framework-based synthesis and summarised into key domains. Study quality was evaluated using the Critical Appraisal Skills Program tool. RESULTS: Thirty studies (33 articles) from multiple countries and settings (eg, acute care, outpatient) with a diverse range of interviewees (eg, nurses, leadership, staff) were included in the final analysis. Five domains characterised struggling healthcare organisations: poor organisational culture (limited ownership, not collaborative, hierarchical, with disconnected leadership), inadequate infrastructure (limited quality improvement, staffing, information technology or resources), lack of a cohesive mission (mission conflicts with other missions, is externally motivated, poorly defined or promotes mediocrity), system shocks (ie, events such as leadership turnover, new electronic health record system or organisational scandals that detract from daily operations), and dysfunctional external relations with other hospitals, stakeholders, or governing bodies. CONCLUSIONS: Struggling healthcare organisations share characteristics that may affect their ability to provide optimal care. Understanding and identifying these characteristics may provide a first step to helping low performers address organisational challenges to improvement.

Pilot randomised controlled trial to improve hand hygiene through mindful moments.

BACKGROUND: To evaluate the effectiveness of a brief mindfulness intervention on hand hygiene performance and mindful attention for inpatient physician teams. DESIGN: A pilot, pre-test/post-test randomised controlled mixed methods trial. SETTING: One academic medical centre in the USA. PARTICIPANTS: Four internal medicine physician teams consisting of one attending, one resident, two to three interns and up to four medical students. INTERVENTION: A facilitated, group-based educational discussion on how mindfulness, as practised through mindful hand hygiene, may improve clinical care and practices in the hospital setting. MAIN OUTCOMES AND MEASURES: The primary outcome was hand hygiene adherence (percentage) for each patient encounter. Other outcomes were observable mindful moments and mindful attention, measured using the Mindfulness Attention Awareness Scale, from baseline to post-intervention, and qualitative evaluation of the intervention. RESULTS: For attending physicians, hand hygiene adherence increased 14.1% in the intervention group compared with a decrease of 5.7% in the controls (P=0.035). For residents, the comparable figures were 24.7% (intervention) versus 0.2% (control) (P=0.064). For interns, adherence increased 10.0% with the intervention versus 4.2% in the controls (P=0.007). For medical students, adherence improved more in the control group (4.7% intervention vs 7.7% controls; P=0.003). An increase in mindfulness behaviours was observed for the intervention group (3.7%) versus controls (0.9%) (P=0.021). Self-reported mindful attention did not change (P=0.865). CONCLUSIONS: A brief, education-based mindfulness intervention improved hand hygiene in attending physicians and residents, but not in medical students. The intervention was well-received, increased mindfulness practice, and appears to be a feasible way to introduce mindfulness in the clinical setting. Future work instructing clinicians in mindfulness to improve hand hygiene may prove valuable. TRIAL REGISTRATION NUMBER: NCT 03165799; Results.

Pain control with continuous infusion preperitoneal wound catheters versus continuous epidural analgesia in colon and rectal surgery: A randomized controlled trial.

OBJECTIVE: To compare continuous infusion preperitoneal wound catheters (CPA) versus continuous epidural analgesia (CEA) after elective colorectal surgery. METHODS: An open-label equivalence trial randomizing patients to CPA or CEA. Primary outcomes were postoperative pain as determined by numeric pain scores and supplemental narcotic analgesia requirements. Secondary outcomes included incidence of complications and patient health status measured with the SF-36 Health Survey (Acute Form). RESULTS: 98 patients were randomized [CPA (N = 50, 51.0%); CEA (N = 48, 49.0%)]. 90 patients were included [ CPA 46 (51.1%); CEA 44 (48.9%)]. Pain scores were significantly higher in the CPA group in the PACU (p = 0.04) and on the day of surgery (p < 0.01) as well as supplemental narcotic requirements on POD 0 (p = 0.02). No significant differences were noted in postoperative complications between groups, aggregate SF-36 scores and SF-36 subscale scores. CONCLUSIONS: Continuous epidural analgesia provided superior pain control following colorectal surgery in the PACU and on the day of surgery. The secondary endpoints of return of bowel function, length of stay, and adjusted SF-36 were not affected by choice of peri-operative pain control.

CE: Original Research: Does Certification in Vascular Access Matter? An Analysis of the PICC1 Survey.

: Background: Although certification by an accredited agency is often a practice prerequisite in health care, it is not required of vascular access specialists who insert peripherally inserted central catheters (PICCs). Whether certification is associated with differences in practice among inserters is unknown. PURPOSE: The purpose of this study was to gather information regarding whether certified and noncertified PICC inserters differ with respect to their practices and views about PICC use. METHODS: We conducted a national survey of vascular access specialists, identifying certified PICC inserters as those who had received board certification from the Association for Vascular Access, the Infusion Nurses Society, or both. The 76-item survey asked about PICC policies and procedures at respondents' facilities, use of insertion technologies, device management, management of complications, perceptions about PICC use, and relationships with other health care providers. Additional data about respondents, including years in practice and primary practice settings, were also gathered. Bivariable comparisons were made using χ tests; two-sided α with P ≤ 0.05 was considered statistically significant. RESULTS: Of the 1,450 respondents in the final sample, 1,007 (69%) said they were certified inserters and 443 (31%) said they were not. Significantly higher percentages of certified than noncertified inserters reported having practiced for five or more years (78% versus 54%) and having placed 1,000 or more PICCs (58% versus 32%). Significantly more certified than noncertified inserters also reported being the vascular access lead for their facility (56% versus 44%). Reported practice patterns for insertion, care, and management of PICCs varied based on certification status. Some evidence-based practices (such as the use of ultrasound to measure catheter-to-vein ratios) were more often reported by certified inserters, while others (such as the use of maximal sterile barriers during PICC insertion) were not. Asked about their perceptions of PICC use at their institution, certified inserters reported higher percentages of inappropriate insertion and removal than noncertified inserters. CONCLUSION: Certified PICC inserters appear to be a distinct group of vascular access specialists. A better understanding of how and why practices differ between certified and noncertified inserters is necessary to ensuring safer, high-quality patient care.

Variation in use of technology among vascular access specialists: an analysis of the PICC1 survey.

BACKGROUND: While the use of technologies such as ultrasound and electrocardiographic (ECG) guidance systems to place peripherally inserted central catheters (PICCs) has grown, little is known about the clinicians who use these tools or their work settings. METHODS: Using data from a national survey of vascular access specialists, we identified technology users as PICC inserters that: (a) use ultrasound to find a suitable vein for catheter placement; (b) measure catheter-to-vein ratio; and (c) use ECG for PICC placement. Individual and organizational-level characteristics between technology users versus non-users were assessed. Bivariable comparisons were made using Chi-squared or Fisher's exact tests; two-sided alpha with p<0.05 was considered statistically significant. RESULTS: Of the 2762 PICC inserters who accessed the survey, 1518 (55%) provided information regarding technology use. Technology users reported greater experience than non-technology users, with a higher percentage stating they had placed >1000 PICCs (55% vs. 45%, p<0.001). A significantly greater percentage of technology users also reported being certified in vascular access by an external agency than non-technology users (75% vs. 63%, p<0.001). Technology users were more often part of vascular access teams with ≥10 members compared to non-technology users (35% vs. 22%, p<0.001). Some practices also varied between the two groups: for example, use of certain securement devices and dressings differed between technology users and non-users (p<0.001). CONCLUSIONS: Technology use by vascular access clinicians while placing PICCs is associated with clinician characteristics, work setting and practice factors. Understanding whether such differences influence clinical care or patient outcomes appears necessary.

The relationship between perceived role and appropriate use of peripherally inserted central catheters: A survey of vascular access nurses in the United States.

BACKGROUND: The presence and proliferation of vascular access nursing in hospital settings has been identified as a potential contributor to growing demand, and possible overuse, of peripherally inserted central catheters (PICCs). OBJECTIVE: We examined vascular access nurses' perceived role related to use of PICCs and the association with appropriateness of PICC use in hospitals. DESIGN: A web-based survey was administered to members of two vascular access professional organizations. PARTICIPANTS: Of 2762 potentially eligible respondents who accessed the link, 1698 (61%) completed the survey. This sample was further restricted to vascular access nurses who worked in a U.S. hospital (n=1147). METHODS: Respondents were categorized based on perceived role: 1) an operator who inserts PICCs; 2) a consultant whose views are not valued by the care team (unvalued consultant); 3) a consultant whose views are valued by the care team (valued consultant). Facility and respondent characteristics, reported practices, leadership support and relationships with other providers were compared across groups using chi-squared tests and analysis of variance. Multivariable logistic regression was used to assess the association between perceived role and reported percentage of PICCs placed for inappropriate reasons. RESULTS: Among the 1147 respondents, 210 (18%) viewed themselves as operators, 683 (59%) as valued consultants, 236 (21%) as unvalued consultants, and 18 (2%) could not be categorized. A significantly higher percentage (93%) of valued consultants reported that vascular access nurses placed the majority of PICCs at their facility, compared to operators (83%) or unvalued consultants (76%) (p<0.001). After adjustment, compared with operators, valued consultants were significantly more likely to report that <10% of PICCs at their facility were inserted for inappropriate reasons (OR 1.7, p=0.002); the finding was reversed for unvalued consultants (OR 0.69, p=0.06). CONCLUSIONS: Vascular access nurses and their perceived role as part of the healthcare team are associated with PICC use in hospitals. Strong inter-professional collaboration and respect may help ensure more appropriate use of PICCs.

Challenges for Nurses Caring for Individuals with Peripherally Inserted Central Catheters in Skilled Nursing Facilities.

OBJECTIVES: To understand the perceived preparedness of frontline nurses (registered nurses (RNs), licensed practical nurses (LPNs)), unit nurse managers, and skilled nursing facility (SNF) administrators in providing care for residents with peripherally inserted central catheters (PICCs) in SNFs. DESIGN: Exploratory, qualitative pilot study. SETTING: Two community based SNFs. PARTICIPANTS: Residents with PICCs, frontline nurses (RNs, LPNs), unit nurse managers, and SNF administrators. METHODS: Over 36 weeks, 56 residents with PICCs and their nurses were observed and informally interviewed, focusing on PICC care practices and documentation. In addition, baseline PICC data were collected on placement indication (e.g., antimicrobial administration), placement setting (hospital vs SNF), and dwell time. Focus groups were then conducted with frontline nurses and unit nurse managers, and semistructured interviews were conducted with SNF administrators to evaluate perceived preparedness for PICC care. Data were analyzed using a descriptive analysis approach. RESULTS: Variations in documentation were observed during weekly informal interviews and observations. Differences were noted between resident self-reported PICC concerns (quality of life) and those described by frontline nurses. Deficiencies in communication between hospitals and SNFs with respect to device care, date of last dressing change, and PICC removal time were also noted. During focus group sessions, perceived inadequacy of information at the time of care transitions, limited availability of resources to care for PICCs, and gaps in training and education were highlighted as barriers to improving practice and safety. CONCLUSION: Practices for PICC care in SNFs can be improved. Multimodal strategies that enhance staff education, improve information exchange during care transitions, and increase resource availability in SNFs appear necessary to enhance PICC care and safety.

Incarcerated fracture fragments of Longevity polyethylene liners after total hip arthroplasty.

Highly cross-linked polyethylene liners are widely used in total hip arthroplasty because they experience lower wear rates than conventional polyethylene liners. However, the cross-linking process does decrease the resistance of polyethylene to fatigue failure and fracture. This report describes 2 cases of highly cross-linked polyethylene liner fracture occurring in association with hip dislocation and unsuccessful closed reduction consequent to blockage by an incarcerated liner fragment. These cases highlight the known polyethylene fracture risk factors of thin and unsupported polyethylene and large bearing sizes. They also reinforce the importance of a careful evaluation of postreduction radiographs for the presence of a concentric reduction and provide a possible explanation for postoperative hip instability, multiple dislocations, and incomplete seating of the femoral head on attempts at closed reduction.

Patients Prefer Propofol to Midazolam Plus Fentanyl for Sedation for Colonoscopy: Results of a Single-Center Randomized Equivalence Trial.

BACKGROUND: Common sedation options for colonoscopy include propofol alone or a combination of midazolam and fentanyl. The former usually requires the presence of an anesthesia caregiver. The strategy that optimizes patient satisfaction has not yet been determined. OBJECTIVE: This study was designed to assess whether patient satisfaction at the time of colonoscopy is equivalent for propofol compared with midazolam and fentanyl. DESIGN: In this prospective, single-center, parallel group, single-blind, randomized, equivalence trial (NCT-01488045), 262 patients blinded to treatment received propofol (n = 126) or midazolam plus fentanyl (n = 136) at the time of colonoscopy. A patient satisfaction survey was administered in the recovery room and 1 to 5 days postprocedure. The endoscopist completed a survey immediately postprocedure. SETTINGS: This study was conducted at a tertiary academic hospital with a dedicated colon and rectal surgery division. PATIENTS: Patients over the age of 18 years who were undergoing elective colonoscopy were included in this study. MAIN OUTCOME MEASURES: The primary outcome was patient satisfaction with the colonoscopy. Secondary outcomes included physician and patient perception of patient pain, physician perception of patient tolerance of and difficulty of procedure, procedure duration, percentage of patients with cecal intubation, recovery time, and adverse events. RESULTS: Patient overall satisfaction scores in the recovery room after using the combination of midazolam and fentanyl (n = 136) during colonoscopy were not equivalent to patient satisfaction scores after using propofol (n = 126) alone (mean = 83.9 and 98.0 visual analog scale points) because the 90% CI (-18.5 to -9.6) for the mean treatment difference (-14.1) was completely outside the prespecified range of equivalence (±5 visual analog scale points). Patient pain as reported by the patient and as perceived by the physician and difficulty of the procedure were significantly worse for the midazolam/fentanyl group (n = 136) compared with the propofol group (n = 126). Time in the colonoscopy suite was significantly shorter for the propofol group, but the difference was small (4 minutes). There were no significant differences in percentage with cecal intubation, recovery time, or adverse events. LIMITATIONS: This is a single-institution, single-endoscopist study and is limited by the inability to perform blinding of the endoscopist. CONCLUSIONS: The use of propofol for conscious sedation during colonoscopy is associated with greater patient satisfaction and less pain when compared with midazolam/fentanyl, as perceived by the patient and endoscopist.

Postoperative hyperglycemia and adverse outcomes in patients undergoing colorectal surgery: results from the Michigan surgical quality collaborative database.

PURPOSE: Our objective was to assess the relationship between high blood glucose levels (BG) in the early postoperative period and the incidence of surgical site infections (SSIs), sepsis, and death following colorectal operations. METHODS: The Michigan Surgical Quality Collaborative database was queried for colorectal operations from July 2012 to December 2013. Normoglycemic (BG < 180 mg/dL) and hyperglycemic (BG ≥ 180 mg/dL) groups were defined by using the highest BG within the first 72 h postoperatively. Outcomes of interest included the incidence of superficial, deep, and organ/space SSIs, sepsis, and death within 30 days. Initial unadjusted analysis was followed by propensity score matching and multiple logistic regression modeling after adjusting for significant predictors. Separate analyses were performed for previously diagnosed diabetic and non-diabetic patients. RESULTS: A total of 5145 cases met inclusion criteria, of which 1072 were diabetic. For diabetic patients, there was a marginally significant association between high BG and superficial SSI in the unadjusted analysis (OR = 1.75, p = 0.056), but not in the adjusted analysis (OR = 1.35, p = 0.39). There was no significant relationship between elevated BG and deep SSI, organ/space SSI, sepsis, or death among diabetic patients. For non-diabetic patients, there was a significant association between high BG and superficial SSI (OR = 1.53, p = 0.03), sepsis (OR = 1.61, p < 0.01), and death (OR = 2.26, p < 0.01), but not deep or organ/space SSI. CONCLUSIONS: Following colorectal operations, superficial SSI, sepsis, and death are associated with postoperative serum hyperglycemia in patients without diabetes, but not those with diabetes. Vigilant postoperative BG monitoring is critical for all patients undergoing colorectal surgery.

Is hepato-imino diacetic acid scan a better imaging modality than abdominal ultrasound for diagnosing acute cholecystitis?

BACKGROUND: The role of hepato-imino diacetic acid scan (HIDA) in the diagnosis of acute cholecystitis remains controversial when compared with the more commonly used abdominal ultrasound (AUS). METHODS: The diagnostic imaging workup of 1,217 patients who presented to the emergency department at a single hospital with acute abdominal pain and suspicion of acute cholecystitis was reviewed to calculate the sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) of AUS and HIDA. RESULTS: In patients undergoing both imaging modalities, HIDA had significantly higher sensitivity (90.7% vs 64.0%, P < .001) and specificity (71.4% vs 58.4%, P = .005) than AUS for the diagnosis of acute cholecystitis. Additionally, PPV and NPV of HIDA (56.2% and 95.0%, respectively) were higher than PPV and NPV of AUS (38.4% and 80.0%, respectively) when both imaging modalities were used for the same patient. CONCLUSION: In adults with acute abdominal pain, HIDA significantly increases the accuracy of the correct diagnosis.
