Brief review: Adoption of electronic medical records to enhance acute pain management.

PURPOSE: The purpose of this paper is to examine physician barriers to adopting electronic medical records (EMRs) as well as anesthesiologists' experiences with the EMRs used by the acute pain management service at two tertiary care centres in Canada. SOURCE: We first review the recent literature to determine if physician barriers to adoption are changing given the exponential growth of information technology and the evolving healthcare environment. We next report on institutional experience from two academic health sciences centres regarding the challenges they encountered over the past ten years in developing and implementing an electronic medical record system for acute pain management. PRINCIPAL FINDINGS: The key identified barriers to adoption of EMRs are financial, technological, and time constraints. These barriers are identical to those reported in a systematic review performed prior to 2009 and remain significant factors challenging implementation. These challenges were encountered during our institution's process of adopting EMRs specific to acute pain management. In addition, our findings emphasize the importance of physician participation in the development and implementation stages of EMRs in order to incorporate their feedback and ensure the EMR system is in keeping with their workflow. CONCLUSIONS: Use of EMRs will inevitably become the standard of care; however, many barriers persist to impede their implementation and adoption. These challenges to implementation can be facilitated by a corporate strategy for change that acknowledges the barriers and provides the resources for implementation. Adoption will facilitate benefits in communication, patient management, research, and improved patient safety.

Chronic pain, healthcare utilization, and quality of life following gastrointestinal surgery.

OBJECTIVES: Our aim in this pilot study was to identify potential predictors of chronic post-surgical pain (CPSP) and other outcomes to consider for inclusion in future prospective studies of CPSP following abdominal gastrointestinal surgery. METHODS: We followed 76 surgical patients during this prospective single-centre cohort study. Pain characteristics, health-related quality of life (HRQOL), and healthcare utilization were assessed preoperatively, at six weeks postoperatively, and at six months postoperatively. Statistical analyses included descriptive statistics and repeated measures analysis of variance. RESULTS: Prior to surgery, 42% of patients reported no pain, 18% reported remote pain, and 33% reported pain at the surgical site. Six months after surgery, 29% of patients with preoperative remote pain and 35% of patients with preoperative pain at the surgical site reported CPSP. Pain-related interference declined from the preoperative to postoperative period; however, six months after surgery almost one-third of participants continued to report pain-related interference with mood (28%), sleep (30%), and enjoyment of life (30%). Consistent with studies of other surgical procedures, measures of anxiety and depression were associated with an increased risk of CPSP. During the six months following surgery, 12% of patients visited the Emergency Department, 15% visited non-traditional providers, and 9.2% visited a walk-in clinic for pain. Compared with Canadian norms, HRQOL was poorer in all domains preoperatively, in all domains but mental health six weeks postoperatively, and in most domains six months postoperatively. CONCLUSION: This feasibility study provides a template for future studies of CPSP following gastrointestinal surgery. Results suggest a substantial burden of persistent pain, healthcare utilization, and decreased HRQOL. Larger-scale studies that are similarly designed will serve to identify predictors of CPSP in this surgical population.

Emergency department use and hospital admission in children following ambulatory surgery: a retrospective population-based cohort study.

Introduction: Paediatric ambulatory surgery (same day surgery and planned same day discharge) is more frequently being performed more in Canada and around the world; however, after surgery children may return to hospital, either through the emergency department (ED) or through a hospital admission (HA). The aim of this study was to determine the patient characteristics associated with ED visits and HA in the 3 days following paediatric ambulatory surgery. Methods: This population-based retrospective cohort study used de-identified health administrative database housed at ICES and included residents of Ontario, younger than 18 years of age, who underwent ambulatory surgery between 2014 and 2018. Patients were not involved in the design of this study. The proportion of ED visit and HA were calculated for the total cohort, and the type of surgery. The ORs and 95% CIs were calculated for each outcome using logistic regression. Results: 83 468 children underwent select ambulatory surgeries. 2588 (3.1%) had an ED visit and 608 (0.7%) had a HA in the 3 days following surgery. The most common reasons for ED visits included pain (17.2%) and haemorrhage (10.5%). Reasons for HA included haemorrhage (24.8%), dehydration (21.9%), and pain (9.1%). Conclusions: Our findings suggest that pain, bleeding and dehydration symptoms are associated with a return visit to the hospital. Implementing approaches to prevent, identify and manage these symptoms may be helpful in reducing ED visits or hospital admissions.

Pain and haemorrhage are the most common reasons for emergency department use and hospital admission in adults following ambulatory surgery: results of a population-based cohort study.

BACKGROUND: Advances in healthcare delivery have allowed for the increase in the number of ambulatory surgery procedures performed in Canada. Despite these advances, patients return to hospital following discharge. However, the reason for unplanned healthcare use after ambulatory surgery in Canada is not well understood. AIMS: To examine unplanned healthcare use, specifically emergency department visit and hospital admissions, in the 3 days after ambulatory surgery in Ontario, Canada. METHODS: This population-based retrospective cohort study was conducted using de-identified administrative databases. Participants were residents in the province of Ontario, Canada; 18 years and older; and underwent common ambulatory surgical procedures between 2014 and 2018. The outcomes included emergency department (ED) visit and hospital admission. Incidence rates were calculated for the total cohort, for each patient characteristic and for surgical category. The odds ratios and 95% confidence intervals were calculated for each outcome using bivariate and multivariate logistic regression. RESULTS: 484,670 adults underwent select common surgical procedures during the study period. Patients had healthcare use in the first 3 days after surgery, with 14,950 (3.1%) ED visits and 14,236 (2.9%) admissions. The incidence of ED use was highest after tonsillectomy (8.1%), cholecystectomy (4.2%) and appendectomy (4.0%). Incidence of admissions was highest after appendectomy (21%). Acute pain (19.7%) and haemorrhage (14.2%) were the most frequent reasons for an ED visit and "convalescence following surgery" (49.2%) followed by acute pain (6.2%) and haemorrhage (4.5%) were the main reasons for admission. CONCLUSIONS: These findings can assist clinicians in identifying and intervening with patients at risk of healthcare use after ambulatory surgery. Pain management strategies that can be tailored to the patient, and earlier follow-up for some patients may be required. In addition, administrative decision-makers could use the results to estimate the impact of specific ambulatory procedures on hospital resources for planning and allocation of resources.

Barriers and facilitators to postoperative pain management in Rwanda from the perspective of health care providers: A contextualization of the theory of planned behavior.

AIMS: Identify opportunities to improve knowledge translation for post-operative pain management in Rwanda by exploring clinician and environmental factors affecting this practice. METHODS: The theory of planned behavior (TPB) guided development of a questionnaire to measure intent to assess and treat postoperative pain. Focus groups and individual interviews were used to contextualize the final questionnaire and generate questions related to pain management practice. Health care providers from two Rwandan teaching hospitals involved in postoperative pain management completed the TPB questionnaire in May 2015. TPB subscale scores were analyzed to identify demographic and practice characteristics associated with intention to treat pain. The general linear model was used to test effect of attitudes, subjective norms, and perceived control on behavioral intent to treat pain. RESULTS: Forty-six percent of participants (N = 131) had training in acute pain management, 56% used a pain protocol, and 74% used pain scales. Tramadol (78%), morphine (79%), and paracetamol (75%) were used most often to treat pain. Drug availability was the most frequently reported barrier to treating pain. Though intention to treat pain was high, only attitudes and perceived control about assessing pain were associated with intention to treat pain. The theme of fear of the adverse effects of pain medications was consistent across focus groups and interviews in both sites. CONCLUSIONS: System and knowledge barriers exist: interventions to address these barriers may lead to improved postoperative pain care. Further validation of the TPB questionnaire is required to address cultural and language factors specific to the Rwandan context.

But: Améliorer le transfert des connaissances en matière de prise en charge de la douleur postopératoire au Rwanda en étudiant les facteurs environnementaux et les facteurs liés aux cliniciens qui affectent cette pratique.Méthodes: La théorie du comportement planifié (TCP) a guidé l'élaboration d'un questionnaire visant à mesurer l'intention d'évaluer et de traiter la douleur postopératoire. Des groupes de discussion et des entrevues individuelles ont été utilisées afin de contextualiser le questionnaire final et formuler des questions portant sur les pratiques en matière de gestion de la douleur. Les prestataires de soins de deux hôpitaux universitaires rwandais impliqués dans la prise en charge de la douleur postopératoire ont répondu au questionnaire fondé sur la TCP en mai 2015. Les scores obtenus pour les sous-échelles ont été analysés afin de cerner les caractérisriques démographiques et les caractéristiques liées aux pratiques qui étaient associées à l'intention de traiter la douleur. Le modèle linéaire général a été utilisé afin de tester l'effet des attitudes, des normes subjectives et du contrôle perçu sur l'intention comportementale de traiter la douleur.Résultats: Quarante-six pour cent des participants (N = 131) avaient une formation en prise en charge de la douleur aigue, 56 % utilisaient un protocole de prise en charge de la douleur et 74 % utilisaient des échelles d'évaluation de la douleur. Le tranadol (78 %), la morphine (79 %) et le paracétamol (75 %) étaient le plus souvent utilisés pour traiter la douleur. La disponibilité des médicaments était la barrière au traitement de la douleur la plus fréquemment citée. Bien que l'intention de traiter la douleur était élevée, seules les attitudes et le contrôle perçu au sujet de l'évaluation de la douleur étaient associés à l'intention de traiter la douleur. Le thème de la peur des effets indésirables des médicaments contre la douleur a été soulevé dans tous les groupes de discussions et les entrevues tenus dans les deux sites.Conclusions: Il existe des barrières systémiques et des barrières liées aux connaissances : des interventions visant à lever ces barrières pourraient mener à l'amélioration des soins postopératoires. Le questionnaire fondé sur la TCP doit être validé davantage afin d'aborder les facteurs liés à la culutre et au langage spécifiques au contexte rwandais.

Safety Perceptions of Health Care Leaders in 2 Canadian Academic Acute Care Centers.

OBJECTIVES: An estimated 7.4% of patients admitted to acute care facilities in Canada experience injury or death due to health care mishaps, and 38% of these events are deemed preventable. Commitment of executive leaders to a culture of safety is important for the reduction of risk to Canadian patients. The purpose of this study was to examine the safety climate from a leader's perspective in 2 Canadian acute care settings, with attention paid to high reliability organization (HRO) principles. METHODS: The Patient Safety Culture in Healthcare Organizations questionnaire was administered to leaders in 2 acute care hospitals in Ontario between June and January 2009. The primary outcome measures were senior leadership support for safety and supervisory leadership support for safety. Misalignment between the safety climate and HRO principles was defined as greater than 10% of respondents reporting problematic or neutral leadership support for safety. RESULTS: Of the 142 respondents (67% response rate), both medical/nursing leaders and tertiary care clinical leaders were significantly more likely than board/administrative leaders to report problematic/neutral responses. Overall, executive leadership perceptions of the safety climate were not aligned with HRO principles. CONCLUSIONS: The significant differences in response between board/administrative leaders and those involved in frontline patient care suggest that a weak safety culture exists in these 2 health care organizations. The cultivation of a stronger organizational safety culture, in alignment with HRO principles, could lead to lower rates of preventable mishaps and support risk identification and mitigation in perioperative settings.

Pain, health-related quality of life and health care utilization after inpatient surgery: a pilot study.

BACKGROUND: Little is known about pain-related outcomes in surgical inpatients after discharge from the hospital. An ongoing risk and outcomes monitoring system would provide valuable feedback to improve the quality of patient care. OBJECTIVES: The purpose of the present pilot study was to describe postoperative pain, medication use, health care utilization and health-related quality of life (HRQOL) immediately and four weeks after surgery; merge clinically captured data with Web-based follow-up data; and examine patients' willingness to complete Web-based health questionnaires. METHODS: One hundred two consecutive surgical inpatients were approached for participation. Perioperative data were abstracted from the acute pain management service clinical database and linked to follow-up data captured four weeks postoperatively. RESULTS: Follow-up questionnaires were completed by 88 participants. Clinical assessment data were successfully linked to Web-based follow-up data. Average pain intensity (3.7) four weeks following discharge fell just short of the acute pain management service active pain score of 3.9. At four weeks, all 88 participants reported significantly impaired HRQOL, 36 were still taking pain medications and 15 had visited an emergency room. Two-thirds of the participants had access to the Internet at home and approximately one-half were willing to complete on-line health questionnaires. DISCUSSION: The study indicates that it is feasible to link clinical and research data, and shows a significant burden of pain and reduced HRQOL in the weeks following discharge. This approach to converting clinically captured data into meaningful information about surgical outcomes is valuable in the development of an ongoing risk and outcomes monitoring system.

Self-reported patient safety competence among Canadian medical students and postgraduate trainees: a cross-sectional survey.

BACKGROUND: Quality and patient safety (PS) are critical components of medical education. This study reports on the self-reported PS competence of medical students and postgraduate trainees. METHODS: The Health Professional Education in Patient Safety Survey was administered to medical students and postgraduate trainees in January 2012. PS dimension scores were compared across learning settings (classroom and clinical) and year in programme. RESULTS: Sixty-three percent (255/406) of medical students and 32% (141/436) of postgraduate trainees responded. In general, both groups were most confident in their learning of clinical safety skills (eg, hand hygiene) and least confident in learning about sociocultural aspects of safety (eg, understanding human factors). Medical students' confidence in most aspects of safety improved with years of training. For some of the more intangible dimensions (teamwork and culture), medical students in their final year had lower scores than students in earlier years. Thirty-eight percent of medical students felt they could approach someone engaging in unsafe practice, and the majority of medical students (85%) and postgraduate trainees (78%) agreed it was difficult to question authority. CONCLUSIONS: Our results suggest the need to improve the overall content, structure and integration of PS concepts in both classroom and clinical learning environments. Decreased confidence in sociocultural aspects of PS among medical students in the final year of training may indicate that culture in clinical settings negatively affects students' perceived PS competence. Alternatively, as medical students spend more time in the clinical setting, they may develop a clearer sense of what they do not know.

Recommendations for improved acute pain services: Canadian collaborative acute pain initiative.

The Canadian Collaborative Acute Pain Initiative, established in 2002, is a voluntary, multidisciplinary consortium of acute pain health professionals from across Canada whose goal is to improve acute pain management through discussion and consensus. The group met in January 2002 to define strategic areas related to the treatment of acute pain. The areas identified were: the definition of pain; the epidemiology of pain; the concept of an 'ideal' acute pain management service; education; therapeutic options; symptom management; and research and safety. In November 2002, a second meeting was held to develop objectives and recommendations for the management of acute pain based on the defined areas. The outcome of these discussions is summarized in this paper.

The impact of sampling and measurement on the prevalence of self-reported pain in Canada.

BACKGROUND: Pain is an important public health problem in Canada. International estimates of general population pain prevalence range from 2% to 46%. OBJECTIVES: The purpose of this paper is to critically examine the potentially misleading use of overall prevalence estimates in the pain literature and to use two Canadian population-based surveys to assess the impact of sampling and measurement on prevalence. METHODS: Two of the secondary data sets used were the 1996/97 National Population and Health Survey (NPHS) and the Canadian Multicentre Osteoporosis Study (CaMos). This paper is based on the assessment of chronic pain in the NPHS, and the assessment of short term pain using the Medical Outcomes Trust's 36-item health survey and the Health Utilities Index, both collected by CaMos. Data are presented as frequencies and percentages overall and stratified by age and sex. CaMos prevalence estimates were age- and sex-standardized to the NPHS population. RESULTS: The overall prevalence of pain was 39% for one-week pain, 66% for four-week pain and 15% for chronic pain. Women were more likely to report pain than men and the prevalence of pain increased with age. CONCLUSIONS: This study yields useful information about the self-reported responses to a variety of questions assessing pain in the general population. Responses to the different questions likely represent different categories of pain, such as short term versus chronic pain, which in turn may have different epidemiological risk factors and profiles. Longitudinal studies of the epidemiology, predictors and natural history of chronic pain are urgently needed in the Canadian population.

Impact of perioperative pain intensity, pain qualities, and opioid use on chronic pain after surgery: a prospective cohort study.

BACKGROUND AND OBJECTIVES: A better understanding of the pathogenesis of chronic postsurgical pain is needed in order to develop effective prevention and treatment interventions. The objective of this study was to evaluate the incidence and risk factors for chronic postsurgical pain in women undergoing gynecologic surgery. METHODS: Pain characteristics, opioid consumption, and psychologic factors were captured before and 6 months after surgery. Analyses included univariate statistics, relative risks (RRs) and 95% confidence intervals (95% CIs), and modified Poisson regression for binary data. RESULTS: Pain and pain interference 6 months after surgery was reported by 14% (n = 60/433) and 12% (n = 54/433), respectively. Chronic postsurgical pain was reported by 23% (n = 39/172) with preoperative pelvic pain, 17% (n = 9/54) with preoperative remote pain, and 5.1% (n = 10/197) with no preoperative pain. Preoperative state anxiety (RR = 1.8; 95% CI, 1.1-2.8), preoperative pain (pelvic RR = 3.7; 95% CI, 1.9-7.2; remote RR = 3.0; 95% CI, 1.3-6.9), and moderate/severe in-hospital pain (RR = 3.0; 95% CI, 1.0-9.4) independently predicted chronic postsurgical pain. The same 3 factors predicted pain-interference at 6 months. Participants describing preoperative pelvic pain as "miserable" and "shooting" were 2.8 (range, 1.3-6.4) and 2.1 (range, 1.1-4.0) times more likely to report chronic postsurgical pain, respectively. Women taking preoperative opioids were 2.0 (range, 1.2-3.3) times more likely to report chronic postsurgical pain than those not taking opioids. Women with preoperative pelvic pain who took preoperative opioids were 30% (RR = 1.3; 95% CI, 0.8-1.9) more likely to report chronic postsurgical pain than those with preoperative pelvic pain not taking opioids. CONCLUSIONS: Preoperative pain, state anxiety, pain quality descriptors, opioid consumption, and early postoperative pain may be important predictors of chronic postsurgical pain, which require further investigation.

How do patients perceive electronic documentation at the bedside?

Electronic patient records provide an opportunity for real-time access to patient information at the bedside, which has the potential to improve healthcare quality because it would increase efficiency and facilitate best practice. Patients in this study reported that portable computers used at the bedside did not affect the clinician-patient relationship. Many patients thought that the technology was a valuable tool and that it could foster an efficient hospital atmosphere and promote reliable and accurate medical documentation.

A comparison of paper with electronic patient-completed questionnaires in a preoperative clinic.

UNLABELLED: In this unblinded randomized control trial we compared electronic self-administered Pre-Admission Adult Anesthetic Questionnaires (PAAQ) using touchscreen technology with pen and paper. Patients were recruited in the Pre-assessment Clinic if they had completed a PAAQ in the surgeon's office. Patients were randomized to study PAAQ using paper, hand-held computer (PDA), touchscreen desktop computer (kiosk), or tablet. Patients also completed a preference and satisfaction survey. The main outcome measures were percent agreement between the prestudy and study PAAQ and time to completion. Only six of the 366 patients approached refused to participate. The median time to completion of the PAAQ was shortest on the kiosk (2.3 min) and longest on the PDA (3.2 min) (chi2 = 14.5; P = 0.002). The mean agreement between the prestudy and the study PAAQ was approximately 94% across all study arms. The proportion of participants expressing comfort before and after completing the PAAQ increased from 10% to 97% on the computerized arms and from 60% to 64% on the paper arm. Touchscreen computer technology is an accurate, efficient platform for patient-administered PAAQ. Patients expressed comfort using the technology and preference for computerized versus paper for future questionnaires. IMPLICATIONS: Self-administered electronic health questionnaires using touchscreen computer technology are an accurate means of collecting patient information in the preoperative setting and can provide a valuable basis for an electronic perioperative patient record. Patients expressed comfort and satisfaction with this method of questionnaire completion.

Acute pain management services have progressed, albeit insufficiently in Canadian academic hospitals.

PURPOSE: Acute pain management services (APMS) evolved in response to the desire for improved management of postoperative pain. The management of postoperative pain received formal support from international organizations over the past decade and by 1993 half of the Canadian university-affiliated teaching hospitals had implemented an APMS. The purpose of this survey was to describe APMSs in Canadian academic institutions, with specific emphasis on postoperative analgesics, new analgesic methods, training and research. METHODS: Between June 2000 and January 2001, 62 Canadian hospitals affiliated with the 16 Canadian university anesthesiology departments were sent a postal questionnaire. RESULTS: Fifty of the 62 respondents returned a completed questionnaire representing a response rate of 81%. Eighty percent of the hospitals surveyed had at least 200 beds, 90% (45) had implemented an APMS. Anesthesiology was primarily responsible in all 45 hospitals with an APMS. The results presented are based on the 45 centres with an APMS. CONCLUSION: Since the early 1990s the percent of Canadian academic hospitals with an APMS has increased from 53% to 92%. These figures are comparable to the United States. Greater collaboration from nursing and pharmacy, mandatory training for medical and nursing students and residents, and a standardized approach to continuous quality improvement remain necessary.

Definitions of "respiratory depression" with intrathecal morphine postoperative analgesia: a review of the literature.

PURPOSE: To review the postoperative intrathecal morphine (ITM) analgesia literature for their definitions of "respiratory depression" (RD). SOURCE: Medline (1966 - June Week 5 2001) and reference lists were searched for original studies involving bolus-dose ITM for postoperative analgesia, which used "respiratory depression" or similar terms. PRINCIPLE FINDINGS: The search identified 209 studies. These were included if ITM use was appropriate (bolus dose, postoperative analgesia) and the term "respiratory depression" was used, which left 96 studies remaining. Forty-four (46%) did not define "RD" despite using this term. A further 24 (25%) defined RD with respiratory rate (RR) alone. Only 28 (29%) defined RD with more than RR alone. There was no statistically significant association between the presence of a definition for RD with study design, study size or publication period. Also, no significant association existed between rigorousness of RD definitions and the above factors. CONCLUSION: The term "respiratory depression" has no clear definition from a review of the literature on ITM use for postoperative analgesia. While defining RD with bradypnea is superior to having no definition, this is still inadequate. In future research, the consistent use of terms with specific meanings will facilitate understanding the true incidence of ITM's respiratory effects. If "respiratory depression" is used, then an explicit definition of its meaning should be provided. Future research must also address what is clinically significant respiratory impairment from intrathecal opioids, and how to optimally monitor for this. Further delineating their risks vs benefits will allow for more optimal dosing.

A survey of directors of Canadian academic acute pain management services: the nursing team members role--a brief report.

PURPOSE: The purpose of this study was to identify Canadian academic centres with Acute Pain Management Service (APMS), and to describe the nature of nursing involvement on the APMS. METHODS: Departments of Anesthesiology in the 16 Canadian medical schools were contacted to obtain a list of affiliated hospitals and the person most responsible for acute pain. A questionnaire designed to gain insight into nursing involvement on APMS was sent out to the 62 hospitals between June 2000 and January 2001. RESULTS: Seventy-six percent of centres responded and of these 89% (n = 42) had an APMS. In 76% of APMS nursing was involved on the service. Sixty-two percent (n = 26) had a designated nursing team member on the APMS who contributed in the realms of patient care, staff and patient education, and administrative development. The APMS nurse performed patient rounds independently (62%) and with a physician (64%). Decision-making was primarily the responsibility of anesthesiology, however, the APMS nurse (38%) and the bedside nurse (23%) were involved in some centres. The highest educational attainment in the 26 hospitals with an APMS nurse was, diploma RN (27%), BScN (31%) and MSc (12%). The distribution of advance practice nursing was nurse practitioner (12%), clinical nurse specialist (27%), or both (8%). CONCLUSION: Nursing played an important role on the APMS, however, quality acute pain management can only be achieved with continuing efforts by anesthesiology, nursing and hospital administration to support the role of nurses as essential members of the acute pain team.

The relationship between movement-evoked versus spontaneous pain and peak expiratory flow after abdominal hysterectomy.

UNLABELLED: The pathogenesis of postoperative lung dysfunction implies a role for movement-evoked pain (e.g., splinting/hypoventilation because of pain avoidance). However, interactions between evoked pain and respiratory physiology are poorly understood. Thus, we examined the relationship between evoked versus spontaneous pain and one index of pulmonary function. In 25 patients having undergone a hysterectomy, visual analog scale ratings (100 mm) for spontaneous pain (REST) and pain during sitting (SIT), forced expiration (BLOW), and coughing (COUGH) were measured together with peak expiratory flow (PEF) at eight time points during postoperative Days 1 and 2. Secondary outcome measures included oxygen saturation and oxygen requirements. Pain was significantly correlated with PEF for COUGH, SIT, BLOW, and REST at eight, seven, four, and two of the eight studied time points, respectively. Mean visual analog scale scores [SE] for COUGH (26.1 mm [1.7]) and SIT (21.5 mm [1.5]) were greater (P < 0.05) than REST (10.5 mm [0.8]), and COUGH was greater (P < 0.05) than BLOW (16.8 mm [1.3]). All pain measures diminished (P < 0.05), and PEF reductions improved (P < 0.05) across the study period. We hypothesize that the consistent negative correlation of COUGH-evoked pain with PEF is, in part, caused by avoidance of coughing, which ultimately limits deep inspiration, lung reexpansion, and clearance of secretions. IMPLICATIONS: Movement-evoked pain may be an important contributor to postoperative complications, but its mechanisms are poorly understood. This study provides the first evidence that postoperative evoked pain correlates with lung function and highlights the need for future research on mechanisms and implications of this phenomenon.

In Canada, anesthesiologists are less likely to respond to an electronic, compared to a paper questionnaire.

PURPOSE: A randomized unblinded controlled trial was used to assess the utility of electronic questionnaires in a survey of Canadian anesthesiologists. METHODS: Postal or electronic questionnaires were sent between November 2001 and March 2002 to 1,333 anesthesiologists registered with the Canadian Anesthesiologists' Society. The primary outcome measure was the difference in response rates between electronic and postal questionnaires. Secondary outcome measures included a comparison of demographic characteristics, cost, and knowledge and practice regarding prophylactic perioperative beta blockade. RESULTS: The overall response rate was 52%. E-mail participants were half as likely as postal participants to respond to the questionnaire (35% vs 69%, relative risk = 0.51, 95% confidence interval 0.45-0.58). Respondents who provided an e-mail address were younger and more likely to be affiliated with an academic institution. There were no significant differences in responses to knowledge and practice questions. The electronic arm was faster than the postal arm and the cost per reply was one-third the cost of the postal arm (2.50 dollars vs 8.02 dollars). CONCLUSIONS: Electronic surveys are a means of acquiring information from a large number of individuals in a rapid, efficient and cost-effective manner. This methodology may be particularly valid and useful in surveys of participants with similar backgrounds and internet access. However the lower response rates achieved as compared with postal surveys indicates a need to use vigilance when generalizing results to a broader population.

Using a personal digital assistant enhances gathering of patient data on an acute pain management service: a pilot study.

PURPOSE: Handheld computer technology provides a unique opportunity for health care professionals to access real time or near real time patient information and evidence-based resources at the point-of-care. The purpose of this study was to assess one physician's experience using acute pain assessment software on a personal digital assistant (PDA) to assess patients on an acute pain management service (APMS). METHODS: Using a historical control and a "time and motion" study design, comparisons were made on acute pain assessment time and comprehensiveness when patient assessments are documented on a PDA vs the current paper-based method. RESULTS: The study physician (a PDA-user) reported feeling comfortable with the assessment software after five patient assessments. PDA assessments were more likely to contain documentation regarding pain and side effects (e.g., nausea, pruritus, hypotension) than the paper assessments. The median time of the "assessment only" component of the patient encounter was 53 sec longer using the PDA compared to paper (P < 0.00), however, the median "total encounter" (chart review, assessment, documentation) time was 74 sec shorter using the PDA vs paper (P < 0.00). DISCUSSION: The findings of this preliminary study suggest that the PDA is a reliable tool that meets the data management requirements within an APMS setting. This study found that patient assessments documented using acute pain software developed for use on a PDA were as efficient and content-rich as paper assessments. The PDA may even enhance the efficiency of the patient assessment process through the provision of more comprehensive digital data for research, clinical, and administrative needs.
