Are complication rates for elective primary total hip arthroplasty in Ontario related to surgeon and hospital volumes? A preliminary investigation.

OBJECTIVE: To test the hypothesis that complication rates for elective total hip replacement operations are related to surgeon and hospital volumes. DESIGN: Retrospective population cohort study. STUDY COHORT: Patients who had undergone elective total hip replacement in Ontario during 1992 as captured in the Canadian Institute for Health Information database. MAIN OUTCOME MEASURES: In-hospital complications, 1- and 3-year revision rates, 1- and 3-year infection rates, length of hospital stay, and 3-month and 1-year death rates. RESULTS: Surgeons with patient volumes above the 80th percentile (more than 27 hip replacements annually) discharged patients approximately 2.4 days earlier (p < 0.05) than surgeons with volumes below the 40th percentile (less than 9 hip replacements annually) even after adjusting for discharge disposition, hospital volume, patient age, sex, comorbidity and diagnosis. Complication rates requiring hospital readmission and death rates did not differ by surgeon or hospital volume (p > 0.05). CONCLUSIONS: There is no evidence to support regionalization of elective hip replacement surgery in Ontario based on adverse clinical outcomes. Surgeons who perform a large number of total hip replacements are discharging patients earlier than less experienced surgeons, without any-demonstrable increase in complications leading to hospital readmission. The explanation for this observation remains unknown and will require further study.

Effect of the prehospital trauma life support program (PHTLS) on prehospital trauma care.

BACKGROUND: Improvement in trauma patient outcome has been demonstrated after the implementation of the Prehospital Trauma Life Support (PHTLS) program in Trinidad and Tobago. This study was aimed at identifying prehospital care factors that may explain this improvement. METHODS: All patients transferred by ambulance to the major trauma referral hospital had assessment of airway control, oxygen use, cervical (C)-spine control, and hemorrhage control, as well as splinting of extremities during pre-PHTLS (July of 1990 to December of 1991; n = 332) and post-PHTLS periods (January of 1994 to June of 1995; n = 350). Pre-PHTLS data were compared with post-PHTLS data by chi 2 analysis with a p value < or = 0.05 being considered statistically significant. RESULTS: The frequency (%) increased in the post-PHTLS period for airway control (10 vs. 99.7%), C-spine control (2.1 vs. 89.4%), splinting of extremities (22 vs. 60.6%), hemorrhage control (16 vs. 96.9%), and oxygen use (6.6 vs. 89.5%) when no specific problem was identified. When a specific problem was identified in these areas, the post-PHTLS percentage also increased for airway control (16.2 vs. 100%), C-spine control (25 vs. 100%), splinting of extremities (33.9 vs. 100%), hemorrhage control (18 vs. 100%), and oxygen use (43.2 vs. 98.9%). CONCLUSIONS: Prehospital trauma care has changed after the introduction of the PHTLS program as indicated by more frequent airway control, use of oxygen, control of cervical (C)-spine and hemorrhage, as well as splinting of fractures. This finding was evident not only as a routine but particularly when a specific related problem was identified. This change in prehospital care could be responsible for the improved trauma patient outcome after PHTLS.

Trauma patient outcome after the Prehospital Trauma Life Support program.

BACKGROUND: We have previously demonstrated a significant improvement in trauma patient outcome after the Advanced Trauma Life Support (ATLS) program in Trinidad and Tobago. In January of 1992, a Prehospital Trauma Life Support (PHTLS) program was also instituted. This study assessed trauma patient outcome after the PHTLS program. METHODS: Morbidity (length of stay and degree of disability), mortality, injury severity score, mechanism of injury, age, and sex among all adult trauma patients transported by ambulance to the major trauma hospital were assessed between July of 1990 to December of 1991 (pre-PHTLS, n = 332) and January of 1994 to June of 1995 (post-PHTLS, n = 350). RESULTS: Age, sex distribution, percentage blunt injury, and injury severity score were similar for both groups. Mortality pre-PHTLS (15.7%) was greater than post-PHTLS (10.6%). Length of stay and disability were statistically significantly decreased post-PHTLS. Age, injury severity score, and mechanism of injury were positively correlated with mortality in both periods. The previously reported post-ATLS mortality was similar to the pre-PHTLS mortality. CONCLUSIONS: Post-PHTLS mortality and morbidity were significantly decreased, suggesting a positive impact of the PHTLS program on trauma patient outcome.

Ineffectiveness of on-site intravenous lines: is prehospital time the culprit?

The purpose of the present study was to test the association between on-site intravenous fluid replacement and mortality in patients with severe trauma. The effect of prehospital time on this association was also evaluated. The design was that of an observational quasi-experimental study comparing 217 patients who had on-site intravenous fluid replacement (IV group) with an equal number of matched patients for whom this intervention was not performed (no-IV group). The patients were individually matched on their Prehospital Index obtained at the scene and were included in the study if they had an on-site Prehospital Index score > 3 and were transported alive to the hospital. The outcome measure of interest was mortality because of injury. The patients in the IV group had a significantly lower mean age (37 vs. 45 years; p < 0.001) and higher incidence of injuries to the head or neck (46 vs. 32%; p = 0.004), chest (34 vs. 17%; p < 0.001), and abdomen (28 vs. 12%; p < 0.001). The IV group also had a higher proportion of patients injured by motor vehicle crashes (41 vs. 27%; p = 0.003), firearms (9 vs. 2%; p = 0.001), and stabbing (20 vs. 9%; p = 0.001). The rate of extremity injuries (38 vs. 59%; p < 0.001) and falls (12 vs. 40%; p < 0.001) was lower for the IV group. In addition, the mean Injury Severity Score was significantly higher for the IV group (15 vs. 9; p < 0.001). The mortality rates for the IV and no-IV groups were 23 and 6% (p < 0.001). Logistic regression analysis showed that after adjusting for patient age, gender, Injury Severity Score, mechanism of injury, and prehospital time, the use of on-site intravenous fluid replacement was associated with a significant increase in the risk of mortality (adjusted odds ratio = 2.3; 95% confidence interval = 1.02-5.28; p = 0.04). To further evaluate the effect of prehospital time on the association between on-site IV use and mortality, the analysis was repeated separately for the following time strata: 0 to 30 minutes, 31 to 60 minutes, and >60 minutes. The adjusted odds ratios (95% confidence interval) for these strata were 1.05 (0.08-14.53; p = 0.97), 3.38 (0.84-13.62; p = 0.08), and 8.40 (1.27-54.69; p = 0.03). These results show that for prehospital times of less than 30 minutes, the use of on-site intravenous fluid replacement provides no benefit, and that for longer times, this intervention is associated with significant increases in the risk of mortality. The results of this observational study have shown that the use of on-site intravenous fluid replacement is associated with an increase in mortality risk and that this association is exacerbated by, but is not solely the result of, increased prehospital times. Our findings are consistent with the hypothesis that early intravenous fluid replacement is harmful because it disrupts the normal physiologic response to severe bleeding. Although this evidence is against the implementation of on-site intravenous fluid replacement for severely injured patients, further studies including randomized controlled trials are required to provide a definitive answer to this question.

The burden of waiting for hip and knee replacements in Ontario. Ontario Hip and Knee Replacement Project Team.

The objectives of this study were to assess the impact of major joint replacements in reducing pain and disability and to describe the burden of pain and disability that could be avoided by ordering the queues with respect to severity of disease. A secondary goal was to compare the uses of a general health status measure, the Short Form Health Survey (SF-36), and a disease-specific measure, the Western Ontario McMaster Osteoarthritis Index (WOMAC), for accomplishing the objectives. The results are based on interviews with 209 patients before and after they had surgery. Only 15.9% of the patients had surgery within 3 months' waiting time, 19.2% waited 4-6 months, 30.7% waited 7-9 months, and the remaining 34.1% waited a year or more. The waiting times were unrelated to the severity of pain or disability reported in the initial interview. Following surgery, there were large reductions in the WOMAC scores for pain, stiffness and difficulty in functioning. The SF-36 showed substantial improvements in relief from pain and in physical functioning, and reductions in role limitation due to physical problems, but not for scores related to mental health. The WOMAC scores were more responsive to the benefits of surgery than the SF-36 scores. Queuing systems keyed on burden of symptoms could reduce the burden of pain and disability suffered by patients awaiting surgery. The improvements from hip and knee replacements suggest that equitable access for these procedures should be a priority in Ontario.

Enthusiasm or uncertainty: small area variations in the use of mammography services in Ontario, Canada.

STUDY OBJECTIVE: To examine the variation in mammography utilisation in relation to age group and indication across health planning regions in Ontario, Canada. DESIGN: This study includes all women aged 30 and over in Ontario who received a mammogram between July 1, 1990 and December 31, 1991. Data from a sample of 10,000 women aged 50-69 were used to assign mammogram indication as "screening", "possible diagnostic", or "probable diagnostic" based on previous health care utilisation patterns. Age specific rates and age adjusted rates in relation to age group (30-39, 40-49, 50-69, and 70 + years) and region were derived. MAIN RESULTS: Overall, 572,762 women received one or more mammograms. Rates increased from 30-54 years and decreased thereafter. Similar variations were seen in the 40-49 and 50-69 age groups. The ranking in the area specific rates remained consistent for all ages except the 30-39 year range. In relation to indication, the largest variation across regions occurred in the screening group. CONCLUSIONS: Mammography utilisation varies across age groups. The greatest variability is for screening, probably because of physician referral patterns, patient uptake, and perhaps access to mammography. The extent of variation was similar when compared between groups where recommendations were consistent (ages 50-59) and where they were inconsistent (ages 40-49) suggesting that perhaps enthusiasm rather than uncertainty is related to regional variation for this procedure.

Appropriateness of primary total hip and knee replacements in regions of Ontario with high and low utilization rates.

OBJECTIVE: To compare the appropriateness of case selection for primary hip and knee replacements between two regions in Ontario: one with a high population-based utilization rate and one with a low rate. DESIGN: Random audit of medical records sampled from hospital discharge abstracts, with subsequent implicit and explicit criteria-based assessments of the appropriateness of surgery. STUDY POPULATION: People aged 60 years or over who underwent elective, single-joint, non-fracture-related, primary hip or knee replacement between Apr. 1, 1992, and Mar. 31, 1993, at one of seven hospitals in a high-rate region (comprising Brant, Huron and Oxford countries) or one of eight hospitals in a low-rate region (comprising the cities of Scarborough and Toronto). INTERVENTIONS: Structured review of hospital medical records, with additional review of information from surgeons and family physicians' office charts if necessary. Three physicians reviewed patient data and rated the preoperative pain level and functional status of patients, with agreement among at least two reviewers. The proportion of inappropriate cases was then assessed according to explicit criteria defined by a multidisciplinary panel using the delphi process. Profiles of each case were also subjected to independent implicit review by two rheumatologists and two orthopedic surgeons. OUTCOME MEASURES: Proportion of joint replacements deemed inappropriate in the high- and low-rate regions according to either the explicit criteria or the implicit review, as well as preoperative pain levels and functional status of patients in the high- and low-rate regions. RESULTS: Hip replacements were more common among patients sampled in the low-rate region than among those in the high-rate region (57.3% v. 39.3%; p < 0.002), although the patients' baseline characteristics, including severity of preoperative pain and dysfunction, were otherwise similar between the regions. Inappropriate surgery, determined by explicit criteria, was equally uncommon in the two regions (6.4% and 6.1%). On implicit review, the two rheumatologists rated fewer cases as appropriate than did the two orthopedic surgeons (63.0% v. 80.0%; p < 0.001); however, the proportion of cases rated as inappropriate by the subspecialists was similar in the high- and low-rate regions (11.4% and 11.0%, respectively, by the rheumatologists, and 6.3% and 10.4%, respectively, by the orthopedic surgeons). CONCLUSIONS: Patients selected for primary hip or knee replacement are similar in the high- and low-rate regions of Ontario. Inappropriate use of this procedure does not account for the high rate of surgery in some areas. Further studies will be required to determine which other factors account for the regional variations in the utilization rates and whether there is underservicing in low-rate areas.

Development of a measure of physical function for patients with bone and soft tissue sarcoma.

Patients undergoing limb salvage surgery for bone and soft tissue sarcoma of the extremities experience significant physical disability as a result of life-preserving treatment. The existing health status measures do not adequately evaluate physical function from the patient's perspective. This paper presents the developmental studies (item selection, reduction, reliability, validity and responsiveness) of a new measure, The Toronto Extremity Salvage Score (TESS). Patients with bone and soft tissue sarcoma (76 upper and 83 lower extremity) were randomly selected and mailed the TESS. Patients rated the severity and importance of physical disabilities; the response options included a 'not applicable' category and open-ended questions that allowed patients to suggest additional items for inclusion in the questionnaire. Therefore, patient perceptions were used to determine item content. Difficulty and importance frequencies were calculated and items rated 'totally unimportant' or 'not applicable' by 30% of the sample were eliminated. Extra items identified 30% of the time were added to the questionnaire. Internal consistency was evaluated by Cronbach's alpha. Test-retest reliability and validity were evaluated on subsequent patient samples. The intraclass correlation coefficient (ICC) was calculated for test-retest reliability and correlations with The Musculoskeletal Tumour Society Rating Scale (MSTS) were calculated for construct validity. Standardized effect sizes were calculated as a measure of responsiveness. Fifty upper extremity and sixty-six lower extremity patients responded to the mailed questionnaire. No items were eliminated based on importance or not applicable ratings. Sporting activities were identified as additional items in both the upper and lower extremity questionnaire. High internal consistency was demonstrated: 0.94 for the lower and 0.92 for the upper extremity questionnaires respectively. Test-retest reliability was evaluated at multiple time-points and the intraclass correlation coefficient was greater than 0.87 in all instances. Construct validity was shown by a moderate correlation with the MSTS. The effect sizes were large demonstrating responsiveness. The use of patients' perceptions in determining the content of the TESS has resulted in a reliable and valid measure that is able to detect change over time.

The context of measuring disability: does it matter whether capability or performance is measured?

This study assesses the differences between two methods of conceptually framing physical disability questions, using two scenarios (capability and performance). The relationship between capability and performance was explored on the basis of the literature and empirically tested by administering two versions of the Activities Scale for Kids (ASK) to 28 physically disabled children. The capability version asked children what they "could do," whereas the performance version asked what they "did do." Capability was found to exceed performance (p < 0.001) by approximately 18%. The difference may relate to a difference in environmental contexts between the two versions, with performance reflecting abilities in usual (or real life) circumstances and capability reflecting abilities in a defined situation apart from real life. Researchers must, therefore, consider carefully the environmental circumstances in which they wish to evaluate outcomes, and use this information to decide whether to measure capability, performance, or both.

The Quebec Back Pain Disability Scale: conceptualization and development.

The Quebec Back Pain Disability Scale is a new measure of functional disability for patients with back pain. Functional disability was operationalized in terms of perceived difficulty associated with simple physical activities. The content of the scale was developed in several stages, including a literature review, two studies seeking the opinions of patients and experts, pilot testing, and a large, longitudinal study of back pain patients. Forty-eight disability items were extensively studied using standard methods such as test-retest reliability, item-total correlations, and factor analysis, as well as modern techniques based on item response theory. Items that were highly effective in discriminating between different levels of disability were selected for the final, reduced scale. The scale has 20 items, representing six empirically derived categories of activities affected by back pain. Measurement properties of this instrument have been previously discussed.

Predictive validity and internal consistency of the pre-hospital index measured on-site by physicians.

Physiological measures of injury are used as triage tools to identify patients that require treatment in trauma centres. The Pre-Hospital Index (PHI) is based on systolic blood pressure, pulse, respiratory rate, (level of) consciousness, and presence of penetrating injury. The present study evaluated the validity and internal consistency of the PHI. The study was based on 628 patients assessed by physicians at the scene. Mean age was 38.7 years (SD = 24.8), and 65% were male. Motor vehicle collisions caused the injury for 45%. The majority had head/neck (56%) and extremity (45%) injuries. Mean PHI was 4.62 (SD = 5.77), 40% had a PHI of zero, 6% between 1 and 3, 32% between 4 and 7, and 21% greater than 7. The associations between PHI and rates of hospital admission, surgery, ICU treatment, mortality, duration of hospitalization, and length of ICU stay were significant (p < 0.001). A total of 260 (41.4%) patients had major trauma requiring treatment at a trauma centre. A PHI > 3 had 83% sensitivity and 67% specificity for identifying these patients. Internal consistency of the PHI variables was above the acceptable limits. This study has shown that the PHI is a valid and reliable physiological measure of injury severity and field triage tool.

Utilization of health care services by immigrants and other ethnic/cultural groups in Ontario.

OBJECTIVES: This study assesses the accessibility of health care services by immigrants and other ethnic/cultural groups in Ontario, using the 1990 Ontario Health Survey. METHODS: The population sample of 38,519 adults aged 16-64 is weighted to represent the entire non-institutionalized population of the province. Outcome measures were whether the study participants visited a general practitioner's office, a specialist's office, or a hospital's emergency department during the past 12 months. RESULTS: The results showed that while the percentages of participants who ever visited a general practitioner's office during the past 12 months were slightly higher in immigrants and other ethnic/cultural groups, the rates of visits to the specialist's office were quite similar, and the rates of hospital emergency department's visits were often lower (except for aboriginals), than for Canadians. These differences in the utilization of health services across different immigrant and ethnic/cultural groups remained unchanged after controlling for health status (as measured by self-reported health problems) and age differences. However, because the sample sizes in some immigrant and ethnic/cultural groups were small, many of the differences were not statistically significant. CONCLUSIONS: We conclude that while immigrants and other ethnic/cultural groups in Ontario usually had equal access to regular services (e.g., visits to general practitioner's office), they often had lower utilization of hospital emergency departments. However, general purpose surveys have limited utility in assessing reasons of health care utilization amongst different ethnic/cultural groups.

Hospital volume, calendar age, and short term outcomes in patients undergoing repair of abdominal aortic aneurysms: the Ontario experience, 1988-92.

OBJECTIVE: To determine, for abdominal aortic aneurysm surgery, whether a previously reported relationship between hospital case volume and mortality rate was observed in Ontario hospitals and to assess the potential impact of age on the mortality rate for elective surgery. DESIGN: Population based observational study using administrative data. SETTING: All Ontario hospitals where repair of abdominal aortic aneurysm as a primary procedure was performed during 1988-92. PATIENTS: These comprised 5492 patients with unruptured abdominal aortic aneurysms and 1203 patients with ruptured abdominal aortic aneurysms admitted to hospital between 1988-92 for repair of abdominal aortic aneurysm as a primary procedure. MAIN OUTCOMES: In-hospital death and length of in-hospital stay. RESULTS: The case fatality rate was 3.8% for unruptured abdominal aortic aneurysms and 40.0% for ruptured abdominal aortic aneurysms. For unruptured cases, after adjustment for patient and hospital covariates, each 10 case per year increase in hospital volume was related to a 6% reduction in relative odds of death (odds ratio (OR) 0.94, 95% confidence intervals 0.88, 0.99) and 0.29 days reduction (95% CI -0.22, -0.35) in postoperative in-hospital stay. Female sex (OR 1.53, 95% CI 1.08, 2.18) and transfer from another acute care hospital (OR 4.37, 95% CI 2.62, 7.29) were associated with increased case fatality rates among patients in the unruptured category. For ruptured cases, neither the case fatality rate nor postoperative in-hospital stay were significantly related to hospital volume. The case fatality rates increased linearly and substantially with advancing age both for unruptured and ruptured aneurysms, and the excess risk of postoperative death in ruptured as compared to unruptured aneurysms was substantially higher in older patients. CONCLUSION: The relationship between hospital volume and mortality or morbidity was very modest and observed only for elective surgery. Case fatality rates in patients with ruptured abdominal aortic aneurysms remained 10 times higher than for patients with unruptured abdominal aortic aneurysms, despite improvements in overall mortality in comparison to previously published data. More effective detection of aneurysms, including elective repair for those once considered "high risk" older patients, might further reduce the toll from ruptured aortic aneurysms.

Primary hip and knee replacement surgery: Ontario criteria for case selection and surgical priority.

OBJECTIVES: To develop, from simple clinical factors, criteria to identify appropriate patients for referral to a surgeon for consideration for arthroplasty, and to rank them in the queue once surgery is agreed. DESIGN: Delphi process, with a panel including orthopaedic surgeons, rheumatologists, general practitioners, epidemiologists, and physiotherapists, who rated 120 case scenarios for appropriateness and 42 for waiting list priority. Scenarios incorporated combinations of relevant clinical factors. It was assumed that queues should be organised not simply by chronology but by clinical and social impact of delayed surgery. The panel focused on information obtained from clinical histories, to ensure the utility of the guidelines in practice. Relevant high quality research evidence was limited. SETTING: Ontario, Canada. MAIN MEASURES: Appropriateness ratings on a 7-point scale, and urgency rankings on a 4-point scale keyed to specific waiting times. RESULTS: Despite incomplete evidence panellists agreed on ratings in 92.5% of appropriateness and 73.8% of urgency scenarios versus 15% and 18% agreement expected by chance, respectively. Statistically validated algorithms in decision tree form, which should permit rapid estimation of urgency or appropriateness in practice, were compiled by recursive partitioning. Rating patterns and algorithms were also used to make brief written guidelines on how clinical factors affect appropriateness and urgency of surgery. A summary score was provided for each case scenario; scenarios could then be matched to chart audit results, with scoring for quality management. CONCLUSIONS: These algorithms and criteria can be used by managers or practitioners to assess appropriateness of referral for hip or knee replacement and relative rankings of patients in the queue for surgery.

Devolution of hip and knee replacement surgery?

The objectives of this study were to assess trends in referral patterns for joint replacements (JRs) in Ontario between the fiscal year 1988/89 and the fiscal year 1993/94; to assess the redistribution of financial resources if services were provided to residents in the region where they reside; and to estimate the financial implications of the devolution of primary JRs from tertiary-care hospitals to community hospitals. Despite rapid growth in the provision of JRs, there was no significant change in their regional distribution. Community hospitals have increased their share of JRs at the expense of teaching hospitals. For hospitals located in Central east Ontario, the cost of providing JRs to nonresidents increased from $ 5.9 million in 1988/89 to $8.3 million in 1993/94. Devolution of primary JRs requires a minimum reallocation sum of $25.1 million, with potential cost savings of $4.3 million. Many obstacles limit the devolution and local provision of health care services, including modifications to referral patterns and the availability of provider expertise, especially when a substantial redistribution of resources is required. Better clinical data to evaluate outcomes and better patient-specific costing data are required. Devolution of services should be addressed in the context of appropriate institutional compensation for medical education.

Fetal tissue transplantation and abortion decisions: a survey of urban women.

OBJECTIVE: To describe women's attitudes and predicted behaviour regarding the potential for fetal tissue transplantation (FTT) to influence abortion decisions. DESIGNS: Self-administered questionnaire survey by mail. SETTING: Academic family practice in Toronto. PARTICIPANTS: Random sample of 475 women 18 to 40 years of age selected from the family practice registry of an urban teaching hospital. Family physicians were blind to their patients' participation, and investigators were blind to the subjects' identity. Forty questionnaires were undeliverable. Of the remaining 435, 272 (62.5%) were completed. Six of the women were over 40 years of age or did not indicate their age and were excluded, which left 266 (61.1%) questionnaires for analysis. OUTCOME MEASURES: Number of women who would (a) be more likely to have an abortion if they could donate tissue for FTT and (b) feel better or worse about choosing abortion if FTT were an option, and open-ended comments about the potential for FTT to influence abortion decisions. RESULTS: Of the 266 respondents 32 (12.0%) reported that they would be more likely to have an abortion if they could donate tissue for FTT, 178 (66.9%) stated that they would not be more likely to do so, and 56 (21.1%) were uncertain. Of the 122 who indicated that they would consider an abortion if they were pregnant, 21 (17.2%) stated that they would be more likely to have an abortion if they could donate tissue for FTT, 77 (63.1%) replied that they would not be more likely to do so, and 24 (19.7%) were uncertain. The women 25 to 33 years of age were more likely to be influenced by FTT than the younger or older women, and the women 18 to 24 years were more uncertain about the influence of FTT on abortion decisions than the older women. In written responses some of the women felt that FTT might make abortion decisions easier; many were troubled that FTT might be used to justify a morally problematic abortion decision and felt that FTT should not be used to justify abortion. CONCLUSION: The data, the first of their kind gathered from from women, suggest that some women's abortion decisions may be influenced by the option to donate tissue for FTT. Further research is necessary to explore the mechanism of influence.
