Identification of factors associated with morbidity and postoperative length of stay in surgically managed chronic subdural haematoma using electronic health records: a retrospective cohort study
Abstract:IntroductionChronic subdural haematoma (cSDH) tends to occur in older patients, often with significant comorbidity. The incidence and effect of medical complications as well as the impact of intraoperative management strategies are now attracting increasing interest.ObjectivesWe used electronic health record data to study the profile of in-hospital morbidity and examine associations between various intraoperative events and postoperative stay.Design, setting and participantsSingle-centre, retrospective cohort … Show more
“…The significance of these findings on neurosurgical services is clearly apparent. Patients with cSDH exhibit a significant degree of inpatient morbidity [24] that negatively impacts on length of stay. Any increase in this workload will further stress a system that already struggles to cope with the complexities of workload, capacity, referral and repatriation [8].…”
Background
Chronic subdural haematoma (cSDH) is a common neurosurgical pathology frequently occurring in older patients. The impact of population ageing on cSDH caseload has not been examined, despite relevance for health system planning.
Methods
This is a single-centre study from the UK. Operated cases of cSDH (n = 446) for 2015–2018 were identified. Crude and directly standardised incidence rates were calculated. Medline and EMBASE were systematically searched to identify studies reporting on the incidence of cSDH by year, so an estimate of rate of incidence change could be determined. Local incidence rates were then applied to population projections for local catchment area to estimate operated cSDH numbers at 5 yearly intervals due to shifting demographics.
Results
We identified nine studies presenting incidence estimates. Crude estimates for operative cases ranged from 1.3/100,000/year (1.4–2.2) to 5.3/100,000/year (4.3–6.6). When non-operated cases were included, incidence was higher: 8.2/100,000/year (6.0–11.2) to 48/100,000/year (37.7–61.1). Four pairs of studies demonstrated incidence rate increases of 200–600% over the last 50 years, but data was deemed too heterogeneous to generate formal estimate of incidence change. Local crude incidence of operated cSDH was 3.50/100,000/year (3.19–3.85). Directly standardised incidence was 1.58/100,000/year (1.26–1.90). After applying local incidence rates to population projections, case numbers were predicted to increase by 53% over the next 20 years.
Conclusions
The incidence of cSDH is increasing. We project a 53% increase in operative caseload within our region by 2040. These are important findings for guiding future healthcare planning.

“…In order to evaluate the role of PALS data against traditional performance indicators, clinical care metrics, included those previously identified in this series of patients 11 and for cSDH in general by others 12 13 were taken from hospital care records. This included age, gender, independence before admission, American Society of Anesthesiologists score, admission date, referral source (local vs referred), operation date, discharge date, whether they required a reoperation, anticoagulation status and occurrence of an in-hospital complication.…”

“…Patients with cSDH pose an increasing challenge for neurosurgical care, as the condition typically occurs in elderly comorbid populations and, with well-documented changes in population demographics, 10 these numbers may rise. 11 Consequently, methods to monitor and optimise care delivery would be valuable. 12 13 This can be a particular challenge for a service involving multiple healthcare providers or centres.…”
ObjectivesTo explore the frequency and nature of complaints and compliments reported to Patient Advice and Liaison (PALS) in individuals undergoing surgery for a chronic subdural haematoma (cSDH).DesignA retrospective study of PALS user interactions.SubjectsIndividuals undergoing treatment for cSDH between 2014 and 2019.MethodsPALS referrals from patients with cSDH between 2014 and 2019 were identified. Case records were reviewed and data on the frequency, nature and factors leading up to the complaint were extracted and coded according to Healthcare Complaints Analysis Tool (HCAT).ResultsOut of 531 patients identified, 25 (5%) had a PALS interaction, of which 15 (3%) were complaints and 10 (2%) were compliments. HCAT coding showed 8/15 (53%) of complaints were relationship problems, 6/15 (33%) a management problem and 1/15 (7%) other. Of the relationship problems, 6 (75%) were classed as problems with communication and 2 (25%) as a problem with listening. Of the compliments, 9/10 (90%) related to good clinical quality and 1/10 (10%) to staff–patient relationship. Patients were more likely to register a compliment than family members, who in turn were more likely to register a complaint (p<0.005). Complaints coded as a relationship problem had 2/8 (25%) submitted by a patient and 6/8 (75%) submitted by a relative.ConclusionsUsing the HCAT, routinely collected PALS data can easily be coded to quantify and provide unique perspective on tertiary care, such as communication. It is readily suited to quality improvement and audit initiatives.
“…Such tools inform intraoperative and postoperative care as part of the National Emergency Laparotomy Audit (NELA) . Patients with chronic subdural haematomas (cSDH) are often elderly with significant comorbidity 2 . Despite this, there is a paucity of literature pertaining to risk stratification models in this cohort 3 .…”
