RESUMEN

BACKGROUND: Sessile serrated lesions (SSL) account for up to 30% of colorectal carcinoma pathogenesis. With multiple classification changes and improvements in colonoscopy equipment and technique, historical reporting may have underestimated the true incidence of SSLs. This study aimed to determine the incidence of SSLs in patients undergoing colonoscopic investigation in Canterbury, New Zealand over a 1-year period and describe their clinical and pathological characteristics. METHODS: Electronic records were searched to identify all lower endoscopy procedures with polypectomy performed from 1 January 2022 to 1 December 2022 (inclusive). Patients' electronic records were used to collect histological classification, location and size of each polyp removed during their procedure. The primary outcome was the number of procedures that had one or more SSL, adenoma or hyperplastic polyp identified. Secondary outcomes included histological classification, location and size of each polyp removed. RESULTS: There were 4346 procedures completed during the study period. Of these, 64.1% (2786) had a polypectomy and 18.6% (808) had at least one SSL excised. Individual polyp analysis was completed on 9166 polyps and found that 24.0% of polyps removed were SSLs and they were found predominately in the right colon (65.1% right colon, 32.6% left colon, 2.3% rectum). SSLs were typically <10 mm (84.8%). CONCLUSION: This study found a higher incidence of SSLs compared to previous research. These results raise questions regarding whether SLL rates have been historically underestimated, whether SSL detection rate should be included as a key performance indicator and raises further concerns regarding the use of computed tomography colonography as a screening tool.

RESUMEN

BACKGROUND: The bidirectional relationship between disease activity and mental health in inflammatory bowel disease (IBD) has prompted investigations into the efficacy of psychotherapeutic interventions such as Acceptance & Commitment Therapy (ACT) on biopsychosocial outcomes. We aimed to examine the efficacy of an ACT Program (intervention) in comparison to a CBT-Informed Psychoeducation Program (active control) for individuals with IBD and co-existent psychological distress. Both programs were delivered online via a hybrid format (i.e. therapist led and participant-led sessions). METHODS: 120 adults with IBD were randomized to either the intervention (N=61) or active control groups (N=59). Efficacy was determined using Linear Mixed Models for group differences, in rate of changes in study outcomes, between baseline, post intervention, and 3-month follow-up. RESULTS: The primary outcome HRQoL significantly improved in the intervention group when compared with the active control group, with a significantly different rate of change observed from baseline to post intervention (t [190] = 2.15, p = 0.033) in favor of the intervention group with a medium effect size (ß = 0.41, MD = 0.07, 95%CI [0.01, 0.12], p = 0.014). Similarly, the secondary outcome Crohn's disease activity significantly reduced in the intervention group when compared with the active control group, with a significantly different rate of change observed from baseline to 3-month follow-up (t [90] = -2.40, p = 0.018) in favor of the intervention group with a large effect size (ß = -0.77, MD = -9.43, 95%CI [-13.72, -5.13], p < 0.001) p = 0.014). Further, when observing the rate of change in outcomes over time for the groups separately, anxiety symptoms and pain significantly improved in the intervention group only, and conversely, ulcerative colitis activity and stress symptoms significantly improved in the active control group only. All other outcomes (N=14) significantly improved over time in both groups including IBD activity, gastrointestinal unhelpful thinking patterns, visceral anxiety, fatigue interference, fatigue severity, fatigue frequency, psychological inflexibility, self-efficacy, resilience, current health status, depression symptoms, IBD control, and pain catastrophizing, however these changes were not significantly different between the groups. CONCLUSION: Both programs were of benefit to people with IBD and distress. However, ACT offers a significant added benefit for HRQoL and self-reported Crohn's disease activity and may be a useful adjuvant therapy in integrated IBD care.

RESUMEN

AIM: To assess the equity of care of patients with non-traumatic dental presentations (NTDP) to Christchurch Emergency Department (ED) in Aotearoa New Zealand. METHODS: This retrospective observational study reviews NTDP to Christchurch ED over a 2-year period (2018-2020). ED and hospital outcomes were compared for Maori, Pacific peoples and NZ Europeans. Results are interpreted utilising Te Ao Maori principles and discussed referencing a Kaupapa Maori framework. RESULTS: There were a total of 2,034 NTDPs, with Maori (27.0%) and Pacific peoples (6.9%) being over-represented compared to local population estimates (9.4% and 3.2% respectively). Maori experienced shorter wait times (45 minutes, 95% CI 22-86) compared to NZ Europeans (56 minutes, 95% CI 24-97) and Pacific peoples (54 minutes, 95% CI 23-97). Maori had the highest age-standardised incidence of admission, but shorter hospital length of stay (0.9 days, IQR 0.4-2.3) compared to Pacific peoples (3.8 days, IQR 1.8-3.9) and NZ Europeans (2.0 days, IQR 1.0-3.7). CONCLUSION: This is the first paper to employ a Kaupapa Maori approach examining NTDP patients presenting to the ED. While outcome measures were largely positive, differences in demographic variables indicate upstream failures, specifically barriers to accessing primary oral healthcare and a paucity of Kaupapa Maori initiatives. Further action and accountability are required to provide high-quality, equitable care for Maori.

RESUMEN

BACKGROUND: The incidence of early-onset colorectal cancer (EOCRC) is increasing. International guidelines state that treatment should not differ from that of older patients. Several studies have shown that patients under 50 years are receiving more aggressive treatment, without any survival benefit. We aim to determine if treatment for stages 2 and 3 EOCRC differs from those of late-onset colorectal cancer (LOCRC) patients. METHODS: This was a retrospective, population-based, cohort study of the treatment patterns of patients diagnosed with colorectal cancer in Canterbury, New Zealand, from 2010 to 2021 age <50 years, compared to those aged 60-74 years. RESULTS: A total of 3263 patients were diagnosed with CRC between 2010 and 2021. Following exclusions, we identified 130 EOCRC and 668 LOCRC patients. Stage 2 EOCRC patients are more likely to be offered adjuvant chemotherapy (p = <0.001). Furthermore, EOCRC patients with either stage 2 or 3 disease are more likely to receive multi-agent therapy (p = <0.01), without any associated increase in survival. CONCLUSION: EOCRC patients are given more adjuvant chemotherapy, without a corresponding improvement in outcomes, highlighting a potential for increased treatment-related harms, particularly in stage 2 disease. Clinicians should be mindful of these biases when treating young cancer patients and need to carefully consider treatment-related harms.

RESUMEN

PURPOSE: Accurate documentation is crucial in surgical patient care. Synoptic reports (SR) are structured checklist-based reports that offer a standardised alternative to traditional narrative reports (NR). This systematic review aims to assess the completeness of SR compared to NR in colorectal cancer (CRC) surgery. Secondary outcomes include the time to completion, surgeon satisfaction, educational value, research value, and barriers to implementation. METHODS: Prospective or retrospective studies that assessed SR compared to NR in colorectal cancer surgery procedures were identified through a systematic search of Ovid MEDLINE, Embase (Ovid), CIHNAL Plus with Full Text (EBSCOhost), and Cochrane. One thousand two articles were screened, and eight studies met the inclusion criteria after full-text review of 17 papers. RESULTS: Analysis included 1797 operative reports (NR, 729; SR, 1068). Across studies reporting this outcome, the completeness of documentation was significantly higher in SR (P < 0.001). Reporting of secondary outcomes was limited, with a predominant focus on research value. Several studies demonstrated significantly reduced data extraction times when utilising SR. Surgeon satisfaction with SR was high, and these reports were seen as valuable tools for research and education. Barriers to implementation included integrating SR into existing electronic medical records (EMR) and surgeon concerns regarding increased administrative burden. CONCLUSIONS: SR offer advantages in completeness, data extraction, and communication compared to NR. Surgeons perceive them as beneficial for research, quality improvement, and teaching. This review supports the necessity for development of user-friendly SR that seamlessly integrate into pre-existing EMRs, optimising patient care and enhancing the quality of CRC surgical documentation.

RESUMEN

BACKGROUND: The incidence of early-onset colorectal cancer (EOCRC), diagnosed before age 50, has been rising in many countries in the past few decades. This study aims to evaluate this trend in Aotearoa New Zealand and assess its impact on Maori. METHODS: Crude incidence and age-standardized incidence of colorectal cancer (CRC) was analyzed from all new cases from the Aotearoa New Zealand national cancer registry for the period 2000-2020. Trends were estimated by sex, ethnicity, age group and location of cancer and projections made to 2040. RESULTS: Between 2000 and 2020, there were a total of 56,761 cases of CRC diagnosed in Aotearoa New Zealand, 3,702 of these being EOCRC, with age-standardized incidence decreasing significantly (P = 8.2 × 10- 80) from 61.0 to 47.3 cases per 100,000. EOCRC incidence increased on average by 26% per decade (incidence rate ratio (IRR) 1.26, p = < 0.0001) at all sites (proximal colon, distal colon and rectum), while the incidence in those aged 50-79 years decreased on average by 18% per decade (IRR 0.82, p = < 0.0005), again across all sites. There was no significant average change in CRC incidence in those over 80 years. In Maori, there was no significant change in age-standardized incidence. There was however a significant increase in crude incidence rates (IRR 1.28, p = < 0.0005) driven by significant increases in EOCRC (IRR1.36, p = < 0.0005). By 2040, we predict the incidence of EOCRC will have risen from 8.00 to 14.9 per 100,000 (6.33 to 10.00 per 100,000 in Maori). However, due to the aging population an estimated 43.0% of all CRC cases will be diagnosed in those over 80 years of age (45.9% over 70 years of age in Maori). CONCLUSION: The age-standardized incidence of CRC from 2000 to 2020 decreased in Aotearoa New Zealand, but not for Maori. The incidence of EOCRC over the same period continues to rise, and at a faster rate in Maori. However, with the ageing of the population in Aotearoa New Zealand, and for Maori, CRC in the elderly will continue to dominate case numbers.

RESUMEN

BACKGROUND: Healthcare systems globally face the issue of resource constraints and need for prioritization of elective surgery. Inclusive, explicit prioritization tools are important in improving consistency and equity of access to surgery across health systems. The General Surgical Prioritization Tool developed by New Zealand's Ministry of Health scores patients for elective non-cancer surgery based on surgeon's clinical judgement and patient derived Impact on Life (IoL) scores. This study aims to measure the changes in patient derived IoL scores after common general surgical procedures to enable direct comparison and inform future prioritization. METHOD: This longitudinal observational study enrolled 322 participants who had undergone elective general surgical procedures. Participants were contacted 3 to 9 months after their procedures and requested to complete the IoL questionnaire. The primary endpoint was the change in IoL scores after surgery among the different procedures. RESULTS: Overall, 229/304 (75%) participants responded to the questionnaire and there were no significant baseline differences between responders and non-responders. Patients in the gallbladder treatment group had the greatest improvement in IoL scores. Patients across all ethnic groups had similar changes in IoL scores. Multivariate analysis showed that gallbladder surgery (relative to hernia surgery) and pre-surgery IoL scores significantly predicted improvement. CONCLUSION: The patient reported IoL score recorded at prioritization for surgery all reduced, albeit to varying amounts, after common general surgical procedures. This, combined with the fact that IoL scores predicted post-operative improvement support their inclusion in prioritization tools in addition to surgeon derived components.

RESUMEN

BACKGROUND: Esophagectomy in combination with perioperative multimodal therapy is the cornerstone of modern curative treatment for esophageal adenocarcinoma. The primary aim of this study was to assess the influence of textbook outcome (TO) as a composite quality performance indicator (QPI) and its perioperative parameters on survival in patients who underwent esophagectomy with curative intent. METHODS: Consecutive patients who underwent an esophagectomy between January 2014 and December 2022 at Christchurch Hospital were identified from a prospectively maintained hospital database. Univariable and multivariable analyses were performed to assess prognostic factors for each composite and individual postoperative outcome. Survival analysis was performed to evaluate the influence of these outcomes on overall survival. RESULTS: A total of 108 patients underwent an esophagectomy during the study period. The overall and Clavien-Dindo (CD) grade ≥ 3 postoperative complication rates were 62% and 26%, respectively. The anastomotic leak rate was 6.5% (n = 7). The TO rate, 30-day readmission rate, and 30-day mortality rate were 20%, 13%, and 1%, respectively. Resection margin and nodal disease were found to be independent prognostic factors for reduced survival. CONCLUSION: TO as originally defined and its postoperative parameters of 30-day postoperative complications and 30-day readmission are validated QPIs of esophageal cancer surgery. Updating the postoperative complication parameter to include CD grade ≥ 3 complications resulted in a positive association between achieving TO and increased survival. Our findings support the call to redefine TO based on an update to this parameter, making it a more precise QPI of esophageal cancer surgery.

RESUMEN

BACKGROUND: Watch and wait (W&W) in complete clinical responders after neoadjuvant chemoradiotherapy has increasingly robust data supporting its oncological safety. Recently, studies have assessed the real-world costs of this strategy compared to surgical resection. Our aim was to compare our oncological safety and costs associated with operative and surveillance strategies to international literature. METHODS: Data were retrospectively collected and analysed via electronic health records from March 2014 to March 2021 in Christchurch, New Zealand. Two cohorts were created based on intention to treat. All hospital events were recorded and costed, as well as oncologic outcomes. Our primary endpoints were the cumulative cost of both strategies, 3-year survival rate, and disease-free survival. RESULTS: Forty-eight patients were identified who had rectal cancers resected (OT) with a yPT0N0 pathology, and 42 who were on the wait-and-watch (W&W) audit after having a clinical complete response. After exclusions, we identified 38 OT and 23 W&W patients; the W&W group were more co-morbid (P = 0.05), had worse functional status (P = 0.008), higher BMI (P = 0.34) and more favourable clinical tumour staging (P = 0.01). The operative treatment (OT) group (n = 38) had more acute admissions (34% versus 13% in W&W, P = 0.08, OR 0.29). There was a 35.7% (n = 8 of 23) local recurrence in W&W and none in the OT group (P ≤ 0.001), with successful salvage in the W&W with local recurrence in 71.5% (n = 5 of 7). Three-year distant metastasis-free rate was 97.3% in the OT group and 90.9% in W&W (p = 0.05). Overall survival was 100% (W&W) and 94.7% (OT); (P = 0.019). Care in the OT group cost more than W&W, accounting for local regrowth management; $NZ70,759.56 versus $NZ47,905.52 (P = 0.014). CONCLUSION: This study found better oncological outcomes in the OT group, whilst the W&W group had reduced morbidity and acute bed days. The cost of wait and watch was approximately two-thirds that of operative treatment, even accounting for salvage procedures for local regrowth.

RESUMEN

BACKGROUND: The Royal Australasian College of Surgeons (RACS) aims to achieve Maori health equity and cultural safety within the surgical workforce. The RACS Maori Health Strategy and Action Plans encourage Surgical Education and Training (SET) selection criteria that recognizes and credit applicants who identify as Maori or demonstrate competence in Maori health issues. This study investigates the current SET selection criteria for Maori entering surgical specialties. METHODS: The selection criteria for each surgical speciality for the proposed 2024 intake were examined through a documentary analysis. Criteria were reviewed for applicability to Maori identification and/or cultural competency. RESULTS: Criteria related to Maori identification and/or cultural competency make up 6%, 2%, and 1.5% of Otolaryngology and Head and Neck, General, and Vascular Surgery total SET selection score respectively. Criteria related to Maori identification and/or cultural competency make up 9% and 0.1% of Orthopaedic and Plastics and Reconstructive Surgery ranking scores for interview eligibility respectively. Cardiothoracic Surgery, Paediatric Surgery, Neurosurgery and Urology specialties do not incorporate any criteria appertaining to Maori. Allocation of research-related points determined by authorship may disincentivize Maori trainees. CONCLUSIONS: Some surgical specialties fail to recognize or credit Maori identification and cultural competency in SET selection criteria. There is a need for regular auditing to ensure SET criteria align with the RACS aspirations for Maori health equity and cultural safety within the surgical workforce.

RESUMEN

INTRODUCTION: Anastomotic leak (AL) after colon cancer resection is feared by surgeons because of its associated morbidity and mortality. Considerable research has been directed at predictive factors for AL, but not the anatomic type of colonic resection. Anecdotally, certain types of resection are associated with higher leak rates although there remains a paucity of data on this. This study aimed to determine the AL rate for different types of colon cancer resection to inform decisions regarding the choice of operation. METHODOLOGY: Retrospective analysis of Bowel Cancer Outcome Registry (BCOR) for all colonic cancer resections with anastomosis between January 2007 and December 2020. Demographic, patient, tumour and outcome data were analysed. AL rates were compared among the different colonic procedures with both univariate and multivariate analysis. RESULTS: 20 191 patients who underwent resection with anastomosis for cancer were included in this study. Of these 535 (2.6%) suffered ALs. While the univariate analysis found male sex, procedure type, symptomatic cancers, emergency surgery, unsupervised registrars, conversion to open surgery, medical complications and higher TNM staging were associated with AL, multivariate analysis, found only procedure type remained a significant predictor of AL (total colectomy (OR 4.049, P<0.001), subtotal colectomy (OR 2.477, P<0.001) and extended right hemicolectomy (OR 2.171, P < 0.001)). CONCLUSION: AL is more common in extended colonic resections. With growing evidence of similar oncological outcomes between subtotal colectomy and left hemicolectomy for splenic flexure cancers, more limited resections should be considered. The type of colonic resection should be integrated into prediction tools for AL.

RESUMEN

AIMS: Non-traumatic dental presentations (NTDPs) commonly present to emergency departments (EDs) and may receive orthopantomograms (OPGs, plain X-rays), opiates and antibiotics. "Choosing Wisely" is an international healthcare campaign that aims to reduce unnecessary and low-value patient care. This study aims to identify low-value management of NTDPs. METHODS: Presentations to the Christchurch Hospital ED with dental pain or dental abscess in 2020 were included. Data collected included patient demographics, management and discharge medications. Descriptive statistics were calculated. RESULTS: There were 931 NTDPs during the study period, with over-representation of young adults, Maori, Pacific Peoples and those living in high-deprivation areas. Of these, 343 (37%) received an OPG, of which 24% (83) were considered low value. Of patients managed by ED staff who were not referred to specialist dental services, 258 (42%) were prescribed antibiotics, of whom only half had facial swelling, and 71% received a script for analgesia, of which 78% included an opiate. Seventy-three percent of patients presented outside of normal working hours. Fewer than one in five NTDPs received definitive treatment. CONCLUSIONS: NTDPs may receive non-optimal management in EDs. Continuing to care for NTDPs in this environment may add to increased healthcare costs, access block and poor opioid and antimicrobial stewardship.

RESUMEN

OBJECTIVE: This study aimed to test whether the relative growth rate of subthreshold abdominal aortic aneurysms (AAAs) in the first 24 months of surveillance predicts the risk of future rupture or repair. METHODS: This was a single centre retrospective observational analysis of all small (< 45 mm diameter) and medium (45 - 54 mm in men, 45 - 50 mm in women) AAAs entered into ultrasound surveillance between January 2002 and December 2019, which received ≥ 24 months of surveillance. Relative growth rates were calculated from measurements taken in the first 24 months of surveillance. The Kaplan-Meier method was used to estimate intervention and rupture free proportions five years following diagnosis for AAAs growing by < 5% and by ≥ 5% in the first 24 months of surveillance. Multivariable Cox regression analysis was used to further analyse this relationship by adjusting for factors found to be significantly associated with outcome in univariable analysis. RESULTS: A total of 556 patients with AAAs (409 men, 147 women) were followed for ≥ 24 months. This included 431 small AAAs. Of these, 109 (25.3%) grew by < 5% in the first 24 months of surveillance and had a cumulative event free proportion of 0.98 ± 0.05 at five years compared with 0.78 ± 0.05 for the ≥ 5% growth group (p < .001). Of 125 medium AAAs, 26 (20.8%) grew by < 5% in the first 24 months of surveillance and had a cumulative event free proportion of 0.73 ± 0.11 at five years compared with 0.29 ± 0.13 for the ≥ 5% growth group (p = .024). Baseline diameter and early relative growth rate were strongly and independently predictive of future intervention or rupture with hazard ratios of 9.16 (95% CI 5.98 - 14.03, p < .001) and 4.46 (95% CI 2.45 - 8.14, p < .001), respectively. CONCLUSION: The results suggest that slow expansion of small (< 45 mm) AAAs observed over an isolated 24 month period is indicative of a very low risk of rupture or repair in the medium term. Isolated growth rates may be a useful tool with which to triage low risk AAAs and prevent unnecessary surveillance.

RESUMEN

OBJECTIVE: The recent epidemiology of Kawasaki disease (KD) in New Zealand (NZ) is unknown. Our aim was to describe the incidence, seasonal variation, long-term outcomes and mortality for KD in NZ. DESIGN: Retrospective national database analysis. SETTING: New Zealand. PATIENTS: First hospitalisation and deaths diagnosed with KD. MAIN OUTCOME MEASURES: Data were extracted for all hospital admissions in NZ coded as KD (International Classification of Diseases (ICD)-9 and ICD-10) from the National Minimum Dataset 1 January 2000 to 31 December 2017. Age, sex, ethnicity and associated diagnoses were available to review. Intervention rates for immunoglobulin administration were also analysed. RESULTS: Over the study period, there were 1008 children with initial hospitalisation for KD. The mean age was 39.8 months (SD 37) and 592 (59%) were boys. The annual incidence rate of KD has increased from 12.2 to 19.5 per 100 000 children <5 years old (0.46 case increase per year; 95% CI 0.09 to 0.83). Children of Asian and Pacific Island ethnicities had the highest incidence (51.2 and 26.1/100 000, respectively). The highest growth in incidence was among East Asian children. The case mortality rate was low (12 of 1008, 1.2%); however, Maori were over-represented (6 of 12 deaths). CONCLUSIONS: There is evidence of increasing KD hospitalisation in NZ, similar to recent studies from Northeast Asia and Australia. KD incidence data were available for retrospective review from a national database, but data on complications and outcomes were incomplete. Notification for KD and an active national surveillance system are recommended to improve care. Future work should focus on factors contributing to poorer outcomes in Maori.

RESUMEN

BACKGROUND: A positive association between volume and outcome for certain operations has led to increasing centralization. The latter is associated with a greater travel burden for patients. This study investigated patient preferences for location of care for cancer surgery. METHODS: Two hundred and one participants were recruited from those who have had recent cancer surgery and from general practice or outpatient clinics in both urban and rural locations in the upper South Island of New Zealand. A questionnaire presented participants with a hypothetical scenario of needing cancer surgery and they were asked to indicate their preference of either a hospital 1 or 5 h away. Scenarios evolved in risk of mortality, complications and need for hospital transfer due to a complication. RESULTS: The majority of participants preferred surgery at the closer hospital when there was a negligible difference in risk. Preference shifted to the distant hospital in a linear relationship as the risk of mortality or complications at the closer hospital increased. Respondents were more likely to prefer the distant hospital from the outset if there was a risk of requiring transfer. CONCLUSION: The majority of participants preferred surgery at the closer hospital if risks were comparable but chose to travel as the risk increased and to avoid hospital transfer due to a complication. New Zealand's unique geography and population make it impossible to replicate centralization models from other countries. The drive for improved outcomes must take equity and patient values into consideration.

RESUMEN

BACKGROUND: Gastrectomy with lymphadenectomy in combination with perioperative chemotherapy is the cornerstone of modern curative treatment for gastric adenocarcinoma. The primary objective of this study was to assess the influence of textbook outcome, postoperative complications, and readmission on survival in patients who underwent gastric cancer surgery. METHODS: Consecutive patients who underwent curative and prophylactic gastric resections from 2014 to 2022 at Christchurch Hospital were identified from the hospital database. Multivariable analyses were performed to assess risk factors for each postoperative outcome. A survival analysis was performed to evaluate the influence of these outcomes on overall survival. RESULTS: Seventy-seven patients underwent a gastric resection during the study period. Thirteen were prophylactic resections for E-cadherin gene mutations and 64 were for malignancy. The overall postoperative complication rate was 34%, with an anastomotic leak rate of 8% (n = 6). The 30-day readmission rate, 30-day mortality rate and 90-day mortality rate were 17%, 1%, and 5% respectively. No sociodemographic differences were identified in each outcome. An increasing day-4 CRP trajectory was observed in patients with an anastomotic leak. Postoperative complications and nodal disease were independent prognostic factors for reduced survival. CONCLUSIONS: Textbook outcome, postoperative complications, and readmission are validated quality performance indicators of gastric cancer surgery. Postoperative complications are associated with poor overall survival independent of severity or type. The underlying mechanisms of this influence remain elusive. The aggressive biology of gastric cancer, combined with the surgical morbidity and its negative influence on survival, highlights the importance of ongoing quality improvement.

RESUMEN

AIM: Trauma is one of the leading causes for years of life lost in New Zealand. Its costs to acute care services alone amount to hundreds of millions per year, and it is the main contributor to years of life lost in patients under 40. Since 2016, the Canterbury Trauma Registry has been actively collecting data on all major traumas presenting to Christchurch hospital. This study will aim to define the demographics of trauma laparotomy patients presenting to Christchurch Hospital, and to assess the relationship between missed injuries (MI) on computed tomography (CT) imaging and time to theatre. METHODS: A retrospective study of trauma patient from June 2016 to February 2019. Data for major trauma patients were supplied from the Canterbury Trauma Registry. Data for minor trauma patients were individually selected from the online operative procedures registry. Non-parametric analysis was undertaken with an independent sample Kruskal-Wallis test alongside pairwise comparisons. RESULTS: Sixty trauma laparotomies were performed over 36 months, predominantly male gender (43/60) and under 40 years of age (39/60). Motor vehicle accident (31/60) and knife injuries (10/60) were the most common mechanisms. Fourty-three out of sixty patients received pre-operative CT scans. Fourty out of sixty patients received a CT scan within 2 hours. Large bowel injuries (four cases) and small bowel (three cases) were the most common missed injuries on pre-operative CT. Small bowel injuries are the predominate injury in blunt trauma while diaphragm and liver injuries predominated in penetrating trauma. Four patients did not undergo laparotomy within 24 hours. There is a statistically significant difference (p<0.001) in time to operating theatre between patients with no pre-operative CT and patients with no MI on CT and patients with MI on CT. There is no statistically significant difference (p<0.231) in time to operating theatre in patients with no MI on CT and patients with MI on CT. CONCLUSION: There is no statistically significant difference in time to operation between trauma laparotomy patients with no MI on pre-operative CT to patients with MI on pre-operative CT. There are recognisable injury patterns in trauma patients. There are delays in trauma patients receiving prompt CT imaging. CT imaging can miss life-threatening injury, close patient observation and further examination, and imaging or operative therapy may be required even if initial imaging is reassuring.

RESUMEN

BACKGROUND: The bidirectional relationship between inflammatory bowel disease (IBD) flare-ups and depression/anxiety symptoms has prompted investigations into psychotherapy to improve health-related quality of life (HRQoL) by targeting depression and anxiety. Acceptance commitment therapy (ACT) is effective in improving symptoms of depression and anxiety in people with chronic diseases, yet minimal research has examined ACT's effectiveness for IBD. This study examines the feasibility, acceptability, and preliminary efficacy of the ACTforIBD program, an online program codesigned with consumers to deliver ACT to those with IBD. METHODS: Adults with IBD and symptoms of mild-moderate distress were randomized to ACTforIBD or an active control (psychoeducation) condition. Participants completed 8 weekly, 1-hour sessions, 4 of which were therapist facilitated. Feasibility was based on recruitment and retention and acceptability was derived from postprogram satisfaction measures. Preliminary efficacy was determined by group differences in rate of change in study outcomes from baseline to postprogram. RESULTS: Of 62 participants (89% women, 11% men; mean age  33 years), 55 completed the program (ACTforIBD: n = 26 [83.9%]; active control: n = 29 [93.5%]). Adherence and acceptability were high in the ACTforIBD group, with 80% of participants completing all self-directed modules and 78% of participants expressing satisfaction with the program. Significant and marginally significant group × time interactions were found for anxiety symptoms (b = -1.89; 95% confidence interval, -3.38 to -0.42) and psychological HRQoL (b = -0.04; 95% confidence interval, -0.07 to 0.01), showing decreased anxiety and increased psychological HRQoL in the intervention group. CONCLUSIONS: ACTforIBD is feasible, acceptable, and improved anxiety symptoms, and psychological HRQoL. This highlights the need for a full-scale randomized controlled trial to further examine the program's efficacy.

RESUMEN

OBJECTIVE: To identify factors associated with death secondary to haemorrhage following major trauma. METHODS: A retrospective case-control study was conducted on data from adult major trauma patients attending Christchurch Hospital ED between 1 June 2016 and 1 June 2020. Cases (those who died due to haemorrhage or multiple organ failure [MOF]), were matched to controls (those who survived) in a 1:5 ratio from the Canterbury District Health Board major trauma database. A multivariate analysis was used to identify potential risk factors for death due to haemorrhage. RESULTS: One thousand, five hundred and forty major trauma patients were admitted to Christchurch Hospital or died in ED during the study period. Of them, 140 (9.1%) died from any cause, most attributed to a central nervous system cause of death; 19 (1.2%) died from haemorrhage or MOF. After controlling for age and injury severity, having a lower temperature on arrival in ED was a significant modifiable risk factor for death. Additionally, intubation prior to hospital, increased base deficit, lower initial haemoglobin and lower Glasgow Coma Scale were risk factors associated with death. CONCLUSIONS: The present study reaffirms previous literature that lower body temperature on presentation to hospital is a significant potentially modifiable variable in predicting death following major trauma. Further studies should investigate whether all pre-hospital services have key performance indicators (KPIs) for temperature management, and causes for failure to reach these. Our findings should promote development and tracking of such KPIs where they do not already exist.
