A comparison of patient-reported outcomes among Canadian women having hysterectomies
2023
Purpose
Many indications for hysterectomy can negatively affect patients’ quality of life. This study uses patient-reported outcomes to measure changes in self-reported health among hysterectomy patients.
Method
A prospective cohort of 294 hysterectomy patients completed patient-reported outcomes preoperatively and six months postoperatively in Vancouver, Canada. Patient-reported outcomes measured pelvic health, sexual function, pain, and depression. Changes in health were compared with paired
t
-tests, and multi-variable regression analysis measured associations between patient and clinical factors with postoperative outcomes
Results
Many patients reported improvements in health. Unadjusted analysis found that 65% of participants reported less pelvic distress, 55% reported less pain, and 47% reported less depression symptoms postoperatively. Multivariable regression analysis found that poorer preoperative health was associated with poorer postoperative outcomes in all domains of health measured (
p
-value < 0.01). Postoperative pain scores were lower (less pain) by 0.78 among residents of the most affluent neighborhoods (
p
-value = 0.02) compared to those in less affluent neighborhoods. Postoperative depression scores were 1.58 points worse among participants with endometriosis (
p
-value = 0.03) and 1.02 points worse among participants having abdominal surgery (
p
-value = 0.02).
Conclusion
Many participants reported improvements in pelvic symptoms, pain, and depression after hysterectomy. Lower socioeconomic status patients may be at risk for reporting higher pain after surgery, and endometriosis patients may report higher depression. Further investigation is needed to determine effective interventions for the higher postoperative pain observed in this study for residents of less affluent neighborhoods.

ABSTRACT
BACKGROUND
Inadequate pain assessment is a barrier to appropriate pain management, but single-item “pain screening” provides limited information about chronic pain. Multidimensional pain measures such as the Brief Pain Inventory (BPI) are widely used in pain specialty and research settings, but are impractical for primary care. A brief and straightforward multidimensional pain measure could potentially improve initial assessment and follow-up of chronic pain in primary care.
OBJECTIVES
To develop an ultra-brief pain measure derived from the BPI.
DESIGN
Development of a shortened three-item pain measure and initial assessment of its reliability, validity, and responsiveness.
PARTICIPANTS
We used data from 1) a longitudinal study of 500 primary care patients with chronic pain and 2) a cross-sectional study of 646 veterans recruited from ambulatory care.
RESULTS
Selected items assess average pain intensity (P), interference with enjoyment of life (E), and interference with general activity (G). Reliability of the three-item scale (PEG) was α = 0.73 and 0.89 in the two study samples. Overall, construct validity of the PEG was good for various pain-specific measures (r = 0.60–0.89 in Study 1 and r = 0.77–0.95 in Study 2), and comparable to that of the BPI. The PEG was sensitive to change and differentiated between patients with and without pain improvement at 6 months.
DISCUSSION
We provide strong initial evidence for reliability, construct validity, and responsiveness of the PEG among primary care and other ambulatory clinic patients. The PEG may be a practical and useful tool to improve assessment and monitoring of chronic pain in primary care.

The appropriate timing of hip fracture surgery remains a matter of debate. We sought to estimate the effect of changes in timing policy and the proportion of deaths attributable to surgical delay.
We obtained discharge abstracts from the Canadian Institute for Health Information for hip fracture surgery in Canada (excluding Quebec) between 2004 and 2012. We estimated the expected population-average risks of inpatient death within 30 days if patients were surgically treated on day of admission, inpatient day 2, day 3 or after day 3. We weighted observations with the inverse propensity score of surgical timing according to confounders selected from a causal diagram.
Of 139 119 medically stable patients with hip fracture who were aged 65 years or older, 32 120 (23.1%) underwent surgery on admission day, 60 505 (43.5%) on inpatient day 2, 29 236 (21.0%) on day 3 and 17 258 (12.4%) after day 3. Cumulative 30-day in-hospital mortality was 4.9% among patients who were surgically treated on admission day, increasing to 6.9% for surgery done after day 3. We projected an additional 10.9 (95% confidence interval [CI] 6.8 to 15.1) deaths per 1000 surgeries if all surgeries were done after inpatient day 3 instead of admission day. The attributable proportion of deaths for delays beyond inpatient day 2 was 16.5% (95% CI 12.0% to 21.0%).
Surgery on admission day or the following day was estimated to reduce postoperative mortality among medically stable patients with hip fracture. Hospitals should expedite operating room access for patients whose surgery has already been delayed for nonmedical reasons.

Replacing the Clinical Institute Withdrawal Assessment—Alcohol revised with the modified Richmond Agitation and Sedation Scale for alcohol withdrawal to support management of alcohol withdrawal symptoms: potential impact on length of stay and complications
2024
Purpose
We evaluated impact on length of stay and possible complications of replacing the Clinical Institute Withdrawal Assessment—Alcohol Revised (CIWA-Ar) scale with a slightly modified Richmond Agitation and Sedation Scale (mRASS-AW) to support managing patients admitted with alcohol withdrawal symptoms in a community hospital. Since mRASS-AW is viewed as easier and quicker to use than CIWA-Ar, provided use of mRASS-AW does not worsen outcomes, it could be a safe alternative in a busy ED environment and offer an opportunity to release nursing time to care.
Methods
Retrospective time-series analysis of mean quarterly length of stay. All analyses exclusively used our hospital’s administrative discharge diagnoses database. During April 1st 2012 to December 14th 2014, the CIWA-Ar was used in the ED and in-patient units to guide benzodiazepine dosing decisions for alcohol withdrawal symptoms. After this point, CIWA-Ar was replaced with mRASS-AW. Data was evaluated until December 31st 2020. Primary outcome: mean quarterly length of stay. Secondary outcomes: delirium, intensive care unit (ICU) admission, other post-admission complications, mortality.
Results
N
= 1073 patients. No association between length of stay and scale switch (slope change 0.3 (95% CI − 0.03 to 0.6), intercept change, 0.06 (− 0.03 to 0.2). CIWA-Ar (
n
= 317) mean quarterly length of stay, 5.7 days (95% 4.2–7.1), mRASS-AW (
n
= 756) 5.0 days (95% CI 4.3–5.6). Incidence of delirium, ICU admission or mortality was not different. However, incidence of other post-admission complications was higher with CIWA-Ar (6.6%) than mRASS-AW (3.4%) (
p
= 0.020).
Conclusions
This was the first study to compare patient outcomes associated with using mRASS-AW for alcohol withdrawal symptoms outside the ICU. Replacing CIWA-Ar with mRASS-AW did not worsen length of stay or complications. These findings provide some evidence that mRASS-AW could be considered an alternative to CIWA-Ar and potentially may provide an opportunity to release nursing time to care.

Factors associated with frequent high-cost individuals with cystic fibrosis and their healthcare utilization and cost patterns
2023
Cystic fibrosis (CF) is a progressive multi-organ disease with significant morbidity placing extensive demands on the healthcare system. Little is known about those individuals with CF who continually incur high costs over multiple years. Understanding their characteristics may help inform opportunities to improve management and care, and potentially reduce costs. The purpose of this study was to identify and understand the clinical and demographic attributes of frequent high-costing CF individuals and characterize their healthcare utilization and costs over time. A longitudinal study of retrospective data was completed in British Columbia, Canada by linking the Canadian CF Registry with provincial healthcare administrative databases for the period between 2009 and 2017. Multivariable Cox regression models were employed to identify baseline factors associated with becoming a frequent high-cost CF user (vs. not a frequent high-cost CF user) in the follow-up period. We found that severe lung impairment (Hazard Ratio [HR]: 3.71, 95% confidence interval [CI], 1.49–9.21), lung transplantation (HR: 4.23, 95% CI, 1.68–10.69), liver cirrhosis with portal hypertension (HR: 10.96, 95% CI: 3.85–31.20) and female sex (HR: 1.97, 95% CI: 1.13–3.44) were associated with becoming a frequent high-cost CF user. Fifty-nine (17% of cohort) frequent high-cost CF users accounted for more than one-third of the overall total healthcare costs, largely due to inpatient hospitalization and outpatient medication costs.

Background
Patients with traumatic spinal cord injury (TSCI) experience the healthcare system in a heterogeneous fashion after initial injury. This study performs a retrospective analysis of administrative data to identify patterns of longitudinal healthcare utilization among patients with TSCI in British Columbia, Canada, up to 20 years after initial hospitalization.
Methods
Using population-based administrative databases, adult patients with incident TSCIs were identified between January 2001 and December 2021. Population-based healthcare administrative and demographic data were used to determine physician services (primary care and specialist), hospital admissions (elective surgical, medical, and emergency department), and clinical information. Descriptive summaries measuring healthcare utilization per person year were calculated. Average utilization calculated in person years since the time of injury was compared between those under 65 years of age and those who were over 65, and based on the level of injury (cervical vs. thoracic/lumbar). Latent-class analysis identified characteristics associated with high healthcare utilization.
Results
The cohort included 4132 patients with an incident TSCI. On average, the patients had 18.9 primary care provider (PCP) visits per person year after their injury occurred. Patients had 13.9 specialist visits per person year, of which the most common was with a neurologist. The average rate of hospital admission for all patients was 1.4 visits per year, and emergency department encounters occurred on average were 0.7 visits per year. Patients 65 and over and those with cervical injuries consistently utilized more healthcare resources compared to younger patients and those with thoracic/lumbar injuries (
p
< 0.001). Latent class modelling found that the highest healthcare utilization was among those with cervical spinal cord injuries and who lived in an urban area.
Conclusions
Patients with TSCI had heterogeneous patterns of primary and specialist healthcare utilization up to 20 years after injury. Further analysis revealed that patients who had had cervical injuries and resided in urban centres accessed healthcare resources more frequently.

We measured changes in self-reported health and symptoms attributable to rectal prolapse surgery using patient-reported outcome (PRO) measures.
A prospectively recruited cohort of patients scheduled for rectal prolapse repair in Vancouver, Canada between 2013 and 2021 were surveyed before and 6-months after surgery using seven PROs: the EuroQol Five-Dimension Instrument (EQ-5D-5L), Generalized Anxiety Disorder Scale (GAD-7), Pain Intensity, Interference with Enjoyment of Life and General Activity (PEG), Patient Health Questionnaire (PHQ-9), Fecal Incontinence Severity Index (FISI), Gastrointestinal Quality of Life Index (GIQLI), and the Fecal Incontinence Quality of Life Scale (FIQL).
We included 46 participants who reported improvements in health status (EQ-5D-5L; p < 0.01), pain interference (PEG; p < 0.01), depressive symptoms (PHQ-9; p = 0.01), fecal incontinence severity (FISI; p < 0.01), gastrointestinal quality of life (GIQLI; p < 0.01), and fecal incontinence quality of life (FIQL) related to lifestyle (p = 0.02), coping and behaviour (p = 0.02) and depression and self-perception (p = 0.01).
Surgical repair of rectal prolapse improved patients’ quality of life with meaningful improvements in fecal incontinence severity and pain, and symptom interference with daily activities.
•Rectal prolapse surgery significantly improves patients' quality of life and symptoms.•Fecal incontinence and pain severity were most consistently improved postoperatively.•Patients waiting longer for surgery reported worse pain interference symptoms.•Fecal incontinence and anxiety were least improved for patients from diverse neighbourhoods.

Improving the quality of care of Canadians waiting for elective surgery: an important health care priority
2023
The backlog of cases on surgical wait lists is a substantial problem for surgical patients, their families, surgeons, health care systems and governments. There are several approaches governments can take to improve the health, well-being and surgical outcomes of waiting patients. First, provinces should consider patient-centred approaches to triaging that reflect pain, symptoms or functional gain, and approaches using multidisciplinary teams or centralized triage. Second, governments could provide prehabilitation and mental health supports aligned with patients’ and families’ preferences during unavoidable waits. Wait times are not going to shorten any time soon; provinces should not only find innovative approaches to reducing waits, but also organize services to improve the health and well-being of waiting patients. Such changes will allow for optimization of patients’ surgical outcomes and reduce the complexity of managing the wait list for their surgeons.

Patient-Physician Sex Discordance and “Before Medically Advised” Discharge from Hospital: A Population-Based Retrospective Cohort Study
2024
Patient-physician sex discordance (when patient sex does not match physician sex) has been associated with reduced clinical rapport and adverse outcomes including post-operative mortality and unplanned hospital readmission. It remains unknown whether patient-physician sex discordance is associated with \"before medically advised\" hospital discharge (BMA discharge; commonly known as discharge \"against medical advice\").
To evaluate whether patient-physician sex discordance is associated with BMA discharge.
Retrospective cohort study using 15 years (2002-2017) of linked population-based administrative health data for all non-elective, non-obstetrical acute care hospitalizations from British Columbia, Canada.
All individuals with eligible hospitalizations during study interval.
Exposure: patient-physician sex discordance.
BMA discharge (primary), 30-day hospital readmission or death (secondary).
We identified 1,926,118 eligible index hospitalizations, 2.6% of which ended in BMA discharge. Among male patients, sex discordance was associated with BMA discharge (crude rate, 4.0% vs 2.9%; adjusted odds ratio [aOR] 1.08; 95%CI 1.03-1.14; p = 0.003). Among female patients, sex discordance was not associated with BMA discharge (crude rate, 2.0% vs 2.3%; aOR 1.02; 95%CI 0.96-1.08; p = 0.557). Compared to patient-physician sex discordance, younger patient age, prior substance use, and prior BMA discharge all had stronger associations with BMA discharge.
Patient-physician sex discordance was associated with a small increase in BMA discharge among male patients. This finding may reflect communication gaps, differences in the care provided by male and female physicians, discriminatory attitudes among male patients, or residual confounding. Improved communication and better treatment of pain and opioid withdrawal may reduce BMA discharge.

Background
Laparoscopic cholecystectomy is a high-volume surgery that is an end-stage treatment for gallstones. There is little understanding of the surgery’s effect on the gain in patients’ health relative to its cost. The objective of this study is to measure health gain, cost and cost utility of elective laparoscopic cholecystectomy.
Methods
Participants completed the EQ-5D(3L) pre-operatively and post-operatively. Quality adjusted life years attributable to cholecystectomy were calculated by comparing health state utility values between the pre- and post-operative time points. Laparoscopic cholecystectomy cost was calculated from a health system perspective and included hospital and specialists’ fees (in 2016 Canadian dollars). Cost per QALY was calculated for the entire sample and demographic sub-groups.
Results
The cohort consisted of 135 participants who completed surveys between February 2013 and June 2017. The response rate among eligible patients was 50%. Assuming that health gain accrued to the participant for 25 years after cholecystectomy, the mean gain in QALYs was 1.7430, corresponding to an average cost per QALY of $2102. Older patients, on average, had less gain in QALYs than younger patients.
Conclusion
Laparoscopic cholecystectomies are inexpensive relative to the gains in health they provide patients. The gains in health were not uniform across age categories. These results should provide health system planners confidence that incremental increases in surgical capacity for elective cholecystectomies is beneficial.
