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.

Prevalence and determinants of pain and pain-related disability in urban and rural settings in southeastern Ontario.

BACKGROUND: Canadian chronic pain prevalence estimates range from 11% to 66%, are affected by sampling and measurement bias, and largely represent urban settings. OBJECTIVES: To estimate chronic pain prevalence and factors associated with pain in southeastern Ontario, a region with a larger rural than urban residence. METHODS: A systematic sampling with a random start was used to contact households. A telephone-administered questionnaire using the Graded Chronic Pain Scale, with questions on health care and medication use, health status, depression and demographics, was administered to consenting adults (18 to 94 years of age; mean age 50.2+/-16.6 years). RESULTS: The response rate was 49% (1067 of 2167), with 76% reporting some pain over the past six months. Low pain intensity with low pain interference prevalence was 34% (grade I), high pain intensity with low pain interference was 26% (grade II), and high pain intensity with high pain interference was 17% (grades III and IV). Of those reporting pain, 49% reported chronic pain (ie, pain for a minimum of 90 days over the past six months) representing 37% of the sample. Being female, unmarried, lower income, poorer self-reported health status and rural residence were associated with increasing pain. Once depression was considered in this pain analysis, residence was no longer significant. Lower rates of health care utilization were reported by rural residents. In those reporting the highest pain grades, poor health, greater medication and health care use, depression and more pain sites were associated with higher odds for pain-related disability. CONCLUSION: There is an elevated prevalence of pain in this almost equally split rural/urban region. Further examination of health care utilization and depression is suggested in chronic pain prevalence research.

Pain prevalence in nine- to 13-year-old schoolchildren.

BACKGROUND: Despite significant progress in the epidemiology of chronic pain in adults, major gaps remain in our understanding of the epidemiology of chronic pain in children. In particular, the incidence, prevalence and sensory characteristics of many types of pain in Canadian children are unknown. OBJECTIVES: A study to obtain the lifetime and point prevalence of common acute pains, recurrent pain syndromes and chronic pains was conducted in a cohort of 495 school children, nine to 13 years of age, in eastern Ontario. METHODS: Children reported their pain experiences and described the intensity, affect and duration of the pains experienced over the previous month by completing the Pain Experience Interview -- Short Form. RESULTS: The majority of children (96%) experienced some acute pain over the previous month, with headache (78%) being most frequently reported. Lifetime prevalence for certain acute pains differed significantly by sex (P<0.05). Fifty-seven per cent of children reported experiencing at least one recurrent pain, while 6% were identified as having had or currently having chronic pain. DISCUSSION: The prevalence of acute pain in this Canadian cohort is consistent with international estimates of acute pain experiences (ie, headache) and recurrent pain problems (ie, recurring headache, abdominal pain and growing pains). However, 6% of children reported chronic pain. The self-completed Pain Experience Interview--Short Form provides a feasible administration technique for obtaining population estimates of childhood pain, and for conducting longitudinal studies to identify risk and prognostic factors for chronic pain.

Residents' and program directors' attitudes toward research during anesthesiology training: a Canadian perspective.

We assessed the attitudes of residents and program directors (PD) toward research training in Canadian anesthesiology residency programs. Questionnaires were sent to all 476 anesthesiology residents in Canada and a modified questionnaire was sent to the PD of each of the 16 anesthesiology programs between November 2003 and April 2004. There was a 60% response rate to the resident questionnaire and 95% from the PDs. Eighty-one percent of programs have mandatory research activity, although only 41% of residents think research should be mandatory. A majority of residents were recently involved in a research project. There was a discrepancy between PDs' and residents' views about the availability of some resources to facilitate research. Residents regard the time needed to learn clinical anesthesia, schedule conflicts, inadequate faculty support, and a lack of protected research time as the top barriers to undertaking a research project. PDs do not consider schedule conflicts or a lack of time as important barriers for resident research. Seventy-five percent of residents would prefer to do another academic activity, such as learning transesophageal echocardiography or taking postgraduate programs in education, rather than completing a research project during their residency.

A demand-based assessment of the Canadian anesthesia workforce - 2002 through 2007.

PURPOSE: The number of anesthesia providers required by the Canadian health care system remains controversial. Questions persist regarding both the adequacy of the current supply and what the future demand will be. The purpose of this study was to quantify the number and adequacy of anesthesia providers in 2002, and predict the same for the year 2007. METHODS: All licensed health care facilities potentially employing anesthetic services were identified. On February 1(st), 2002 a questionnaire was mailed to each institution. On April 1(st), a second mailing was sent to non-responders. Those facilities that did not respond to either mailing were contacted by telephone. RESULTS: Responses were obtained from 831 of 891 (93%) health care facilities. Four hundred and twenty-six of the facilities employed anesthetic services. There were 1,610 operating rooms (ORs) in use daily, and 2,134 full-time equivalent (FTE) anesthesia providers were available to the institutions surveyed. Respondents identified an immediate need for 228 additional FTEs. Hospitals with less than five ORs or five FTEs reported higher vacancy rates than hospitals with greater than five ORs or five FTEs (P < 0.0001). Ontario (n = 85) and Quebec (n = 69) had the largest absolute deficits of FTEs and significantly greater odds of vacancies than western provinces (Ontario OR = 1.84, Quebec OR = 2.50). The projected need for 2007 was an additional 560 FTEs. CONCLUSION: This is the first study to survey a national census of "consumers" of anesthetic services: Canadian health care facilities. The results indicate substantial current and worsening future shortages of anesthesia providers in Canada.

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.

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.

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.

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.

Knowledge and practice regarding prophylactic perioperative beta blockade in patients undergoing noncardiac surgery: a survey of Canadian anesthesiologists.

UNLABELLED: A lack of awareness of the "best" current practice is frequently cited as a major barrier to the practice of evidence-based medicine. The purpose of this study was to survey Canadian anesthesiologists to determine their knowledge and practices associated with prophylactic perioperative beta blockade, a therapy that has been widely discussed in the literature and has the potential for a significant positive impact on patient outcomes. We sent questionnaires to 1234 members of the Canadian Anesthesiologists' Society. The overall response rate was 54%. Ninety-five percent of respondents were aware of the perioperative beta blocker literature, and of these, 93% agreed that beta blockers were beneficial in patients with known coronary artery disease (CAD). Fifty-seven percent reported always or usually administering prophylactic beta blockers in patients with known CAD, and 34% of these regular users continued therapy beyond the early postoperative period. Only 9% of respondents reported that a formal protocol existed at their facility. This study suggests that barriers to the translation of research to practice were not related to a lack of awareness of the current best evidence. With respect to perioperative beta blockers, controversies within the literature as well as practical considerations may be greater barriers to implementation of best evidence. IMPLICATIONS: This survey found that anesthesiologists were aware of and supported the use of prophylactic perioperative beta blockers in patients with risk factors or known coronary artery disease; however, only 57% frequently prescribed perioperative beta blockers. A lack of awareness of the current "best" evidence was not a barrier to use.

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.

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.

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.
